The evolution of Arsenal's transfer record
Arsenal have broken their transfer record by spending what Lyon president Jean-Michel Aulas says is close to 50million euros (£44million) on striker Alexandre Lacazette.
Here, Press Association Sport looks at how the Arsenal transfer record has evolved over the last century.
Archie Devine - February 1913, £1,000
Signed from Bradford in a vain bid to avoid relegation in the 1912-13 season, Scotland midfielder Devine scored five goals in 24 games and worked as a miner and dockyard worker after his playing days were over.
David Jack - October 1928, £10,890
Figures vary over the exact amount that Arsenal paid for England striker Jack, who would prove a sensation with 124 goals in 208 games. But it was the first five-digit signing in world football - almost double the previous record - and legend has it that Arsenal boss Herbert Chapman got the Bolton negotiators drunk to bring the fee down.
Peter Marinello - January 1970, £100,000
The Scottish winger was dubbed "the next George Best" on joining from Hibernian and the 19-year-old scored on his debut at Manchester United. But he rarely hit those heights again and left for Portsmouth in 1973 after only five goals and 51 games.
Malcolm Macdonald - July 1976, £333,333
Eclipsing the £220,000 spent on Alan Ball in 1971, Arsenal paid the unusual sum of £333,333.34 on Newcastle striker Macdonald five years later. 'Supermac' won the Golden Boot in 1977 and played 14 times for England before a knee injury cut his career short.
Clive Allen - June 1980, £1.25m
The striker joined from QPR to become Arsenal's first £1m player. Featured in three matches during Arsenal's 1980-81 pre-season, but he did not play a single competitive match for the Gunners before moving to Crystal Palace in a shock swap deal with full-back Kenny Sansom.
David Seaman - May 1990, £1.3m
Arsenal took nearly a decade to raise the bar again, but when they did it was a world transfer record for a goalkeeper. Seaman went on to make 325 Premier League appearances and play more in goal for the Gunners than anyone else.
Ian Wright - September 1991, £2.5m
Arsenal's first £2m player was a larger than life character signed from Crystal Palace after coming out of non-league. The England striker broke Cliff Bastin's club scoring record with 185 goals in 286 appearances before joining West Ham in 1998.
Dennis Bergkamp - June 1995, £7.5m
The last time Arsenal broke the British transfer record (it only stood for a few days as Liverpool paid £8.5m for Stan Collymore), the Gunners got their money's worth. The Dutchman's goals and assists played a central role in the club's success under Arsene Wenger.
Thierry Henry - August 1999, £11m
Another outstanding piece of transfer business as Henry joined from Juventus. Became the club's all-time leading scorer with 228 goals in all competitions before moving on to Barcelona for £24m Euros in 2007.
Mesut Ozil - September 2013, £38.2m
The signing of Ozil, which had the potential to rise by a further £4.3m in add-ons, from Real Madrid almost tripled the previous £15m record purchase of Andrei Arshavin in 2009. But the Germany playmaker has divided opinion in his four seasons in north London.
