Southampton splash out £16m for Boufal
Southampton have signed attacking midfielder Sofiane Boufal from Lille for a club-record fee believed to be in the region of £16m.
The 22-year-old Morocco international has put pen to paper on a five-year contract.
The Moroccan rose through the ranks at Angers, making his debut for the club at 18, before helping the side secure promotion to Ligue 1 in the 2014-15 season.
After that, Boufal moved to Lille, for whom he made 43 appearances and scored 14 goals.
Liverpool, meanwhile, have agreed a £6m deal to sell midfielder Luis Alberto to Lazio.
The Serie A side will pay £4.3m up front with a further £1.7m in add-ons dependent on European qualification. Liverpool have also included a 30pc sell-on clause in the deal.
Alberto, a signing by former manager Brendan Rodgers, failed to establish himself at Anfield after arriving for £6.8m three years ago and made just 12 appearances in his maiden season.
The 23-year-old Spaniard spent the last two campaigns on loan at Malaga and Deportivo La Coruna.
Middlesbrough have agreed a season-long loan with Arsenal for defender Calum Chambers.
The 21-year-old had been linked with a number of clubs, including Hull, Roma and Valencia.
