The busiest club in a transfer window that has sparked into life are Liverpool. Their £29m move for the Hoffenheim forward Roberto Firmino is the league's most expensive deal of the summer so far and the highest-profile of the five completed by Brendan Rodgers. The others have seen James Milner arrive on a free transfer after his contract at Manchester City ran down, the striker Danny Ings arrive from Burnley, the young defender Joe Gomez sign for £3.5m from Charlton and the goalkeeper Adam Bogdan from Bolton.
Manchester United moved to secure the PSV winger Memphis Depay for around £25m in May but are yet to deal further and Tottenham were similarly sharp to sign the Belgian defender Kevin Wimmer. Spurs have also added the Burnley right-back Kieran Trippier to their squad for around £3.5m.
Southampton have been active early on, hiring the Malaga forward Juanmi and the Sporting Lisbon right-back Cedric Soares, while the Fulham goalkeeper Maarten Stekelenburg has arrived on loan.
Spanish attackers have been popular early in the window, with Stoke City bringing in the Hannover player Joselu for £5.75m and Everton completing a £4.2m move for their former loanee Gerard Deulofeu from Barcelona. Also pitching up at Goodison Park is the Manchester United midfielder Tom Cleverley.
Newly-promoted Bournemouth have flexed their muscles early on, signing the Ipswich left-back Tyrone Mings for a club record £8m, with Ryan Fraser moving in the opposite direction on loan.
Other high-profile deals have seen Swansea swoop for the Marseille striker Andre Ayew along with the Saint-Etienne left-back Franck Tabanou, and Aston Villa bring Micah Richards back to England on a permanent deal after his loan from Manchester City to Fiorentina expired. Slaven Bilic's first signing as manager of West Ham has been the highly rated Sampdoria midfielder Pedro Obiang, a deal followed by the arrival of the Marseille forward Dimitri Payet.
It seems a matter of time before Petr Cech joins Arsenal from Chelsea. The same can be said for Nathaniel Clyne's move to Liverpool from Southampton. Manchester United seem likely eventually to get their man in Real Madrid's Sergio Ramos although it could hasten the move in the opposite direction of David de Gea.
The Paul Pogba saga looks sure to run and run, with Manchester City said to be the latest side in the box seat. Tottenham look set to sign Toby Alderweireld, who spent last season with Southampton, when the player returns from his honeymoon. Bournemouth could make a sixth signing of the summer in the experienced former Everton defender Sylvain Distin. Another promoted side, Watford, are likely to sign the Genoa winger Diego Perotti in a deal worth £7m.
Italy's top flight has seen its fair share of high-profile deals already, perhaps riding the wave of Juventus's excellent run to the Champions League final. And it was the Vecchia Signora who struck early in June to sign the Argentinian forward Paulo Dybala from their Serie A rivals Palermo for around £28m. They have also paid nearly £17m for the Atletico Madrid centre-forward Mario Mandzukic and firmed up the signing of on-loan Udinese midfielder Roberto Pereyra.
But perhaps the bargain of the summer so far is the Bosman signing of Sami Khedira, after the German's departure from Real Madrid. Carlos Tevez has ended speculation about his future by confirming that he has re-signed for his first club Boca Juniors.
The second most expensive transfer among Serie A clubs has been Internazionale's £26m move for the Monaco midfielder Geoffrey Kondogbia, who had been linked with Premier League clubs.
Napoli have re-signed the goalkeeper Pepe Reina, their former loanee, after his year deputising for Manuel Neuer at Bayern Munich. Also arriving in Naples is the influential Empoli midfielder Mirko Valdifiori.
One of the most eye-catching deals elsewhere has been Sassuolo's £8m move for an outright claim to the Juventus and Italy under 21 forward Domenico Berardi.
The 20-year-old had been co-owned by the two and scored 42 goals in the last three seasons for Sassuolo. It has been suggested that the Turin club have a buy-back clause for the player.
Roma are yet to make a high-profile signing this summer but have bought back the Italy international midfielder Andrea Bertolacci from Genoa.
Genoa themselves have been busy, signing the former Lazio forward Goran Pandev from Galatasaray to join two other newcomers Serge Gakpe and Darko Lazovic, whose arrivals were confirmed by the club earlier this year.
Juventus midfielder Andrea Pirlo is close to joining Major League Soccer club New York City, while Fiorentina hope to persuade Mohamed Salah, such a success during his loan spell from Chelsea last season, to stick around for another year but the player's high wage demands could mean that Internazionale will step in to secure the Egyptian star's services.
Barcelona have not let the small matter of a transfer embargo prevent them from signing the Sevilla winger Aleix Vidal, although the 25-year-old will not be able to represent them competitively until January.
It can be only a matter of time before Rafa Benitez and Real Madrid spring into action but for now the only significant new face is that of Danilo, whose arrival from Porto was rubber-stamped in March.
The other big piece of business so far is Atletico Madrid's £14m purchase of the Villarreal striker Luciano Vietto, who scored 12 goals in his first La Liga season and will be expected to fill the void left by Mandzukic.
In a cheaper but even bigger-name move Real Betis snapped up the former Hamburg, Real Madrid and Spurs midfielder Rafael van der Vaart.
The Europa League winners, Sevilla, have signed the forward Gael Kakuta from Chelsea, as well as Celta Vigo's Danish midfielder Michael Krohn-Dehli. They have moved Iago Aspas, whom they were obliged to sign after his loan from Liverpool, straight to Celta.
Valencia have also been busy, firming up their loan deals with Benfica to sign Rodrigo, Joao Cancelo and Andre Gomes permanently.
They have also signed the Sao Paulo defensive midfielder Rodrigo Caio. Otherwise the Spanish market has yet to kick fully into gear.
Real Madrid remain strongly linked with the Spain goalkeeper David de Gea, although Manchester United are said to value him at more than £35m.
Paul Pogba's name keeps being mentioned in connection with Spain's big two, especially Barcelona.
Germany's leading powers have been quickly into action, Bayern Munich signing the Stuttgart goalkeeper Sven Ulreich to join his former team-mate Joshua Kimmich, the midfielder whose deal was agreed in January. Stuttgart have replaced Ulreich with the PSV Eindhoven goalkeeper, Przemyslaw Tyton.
Borussia Dortmund have kicked off the post-Jurgen Klopp era with the acquisition of Gonzalo Castro, the Bayer Leverkusen midfielder, while the Freiburg goalkeeper Roman Burki has joined along with the young 1960 Munich midfielder Julian Weigl.
Wolfsburg will be looking to build on their outstanding 2014-15 season and will do so with the services of the former Borussia Monchengladbach striker Max Kruse.
Although Hoffenheim have lost Roberto Firmino, they have gained the outstanding young Czech right-back Pavel Kaderabek from Sparta Prague and the Swiss centre-back Fabian Schar from FC Basel. They have also signed the Freiburg midfielder Jonathan Schmid.
Freiburg have paid a severe price for last season's relegation, losing forward Admir Mehmedi to Bayer Leverkusen, who have also completed a deal for the Schalke defender Kyriakos Papadopoulos. Leaving Leverkusen in another high-profile deal was striker Josip Drmic, who joins Borussia Monchengladbach.
Another move between Bundesliga teams is that of the striker Anthony Ujah, who joined Werder Bremen from Mainz in May. Mainz have looked to Japan for his replacement, signing FC Tokyo's exciting forward Yoshinori Muto. Big things are also expected of the striker Florian Niederlechner, acquired from FC Heidenheim, but they may find it hard to replace the midfielder Johannes Geis, who has joined Schalke.
Bayern Munich look sure to complete a move for the Shakhtar Donetsk forward Douglas Costa, with his club manager, Mircea Lucescu, having confirmed that the deal is imminent.
There have been few big-money deals swilling around in France, with even Paris Saint-Germain keeping their powder dry so far. Departures, particularly to England, seem the norm at the moment although three players have made the return journey: Yacouba Sylla has joined Rennes after an unsuccessful spell at Aston Villa and Kevin Theophile-Catherine has made his loan to Saint-Etienne from Cardiff permanent but the biggest name to be on the move is Hatem Ben Arfa. The former Newcastle player joined Nice in January but was unable to sign for them until June, as he had already played for two teams last season.
Meanwhile, the Belgian winger Nill de Pauw, who had been courted by Charlton, has joined Guingamp from Lokeren. Lille, too, have been active, signing the former Marseille defender Renato Civelli from Bursaspor and the Nice midfielder Eric Bautheac.
Monaco seem sure to confirm the arrival of the Estudiantes striker Guido Carrillo. The Argentinian club have said that the 24-year-old is on his way after the clubs agreed a deal of around £6.3m. The exciting Caen midfielder Thomas Lemar is due to be confirmed as a Monaco player, too. Paris Saint-Germain have been linked with a slew of big-name players but departures - such as Yohan Cabaye and Thiago Motta - could be on the cards first.
There has been next to no significant movement yet from the traditionally big-spending clubs in Russia and Ukraine and Portugal's big guns, too, have generally been holding fire. Benfica announced the signing of Adel Taarabt from QPR on a five-year deal, though, and Porto have signed the Rayo Vallecano and former Derby forward Alberto Bueno.
Holland has seen more activity, with Ajax signing Nemanja Gudelj from AZ and the former Everton defender John Heitinga on a free transfer. Dirk Kuyt's return to Feyenoord was confirmed before the end of last season.
In Turkey, Samuel Eto'o is reportedly on the verge of signing for Antalyaspor. The Lille defender Simon Kjaer's move to Fenerbahce has been confirmed.
