Despite the financial impact of coronavirus, Arsenal made big moves in the summer transfer market.
Their biggest signing came on the very last day of the transfer window: Thomas Partey.
The Ghanaian arrived at the club from Atletico Madrid for £45m, a fee which makes him Arsenal's fourth biggest signing in their history.
So, with that in mind, who are Arsenal's 20 biggest signings ever and how they did they fare?
We've decided to look at their biggest signings and rank them from 'unbelievable' to 'complete flop'.
You can view our selections below...
Pierre-Emerick Aubameyang | Dortmund to Arsenal | £57.38m
Alexis Sanchez | Man United to Arsenal | £38.25m
Two truly brilliant signings.
Aubameyang has netted 72 goals in 114 games for Arsenal, while Sanchez was sensational wherever he lined up.
Bernd Leno | Leverkusen to Arsenal | £22.5m
Santi Cazorla | Malaga to Arsenal | £17.1m
Sylvain Wiltord | Bordeaux to Arsenal | £15.75m
Leno has been one of the best goalkeepers in the Premier League since his arrival in 2018.
Cazorla would have been placed in the unbelievable category had he not suffered from so many long-term injuries.
Arsenal supporters remember Wiltord fondly for his successful four-year spell at the club.
Alexandre Lacazette | Lyon to Arsenal | £47.7m
Mesut Ozil | Real Madrid to Arsenal | £42.3m
Granit Xhaka | Gladbach to Arsenal | £40.5m
Kieran Tierney | Celtic to Arsenal | £24.3m
Jose Antonio Reyes | Sevilla to Arsenal | £18m
Lacazette and Xhaka have both been decent for Arsenal, but you could argue they still haven't lived up to their hefty price tags.
Ozil was brilliant for Arsenal during his first four years from the club. It's just a shame his current situation has tarnished his legacy at the club.
Tierney looks promising but he's suffered from numerous injuries during his short stint.
Reyes (R.I.P) was part of Arsenal's invincible season but failed to truly adapt to English football.
Nicolas Pepe | Lille to Arsenal | £72m
Lucas Torreira | Sampdoria to Arsenal | £25.79m
Calum Chambers | Southampton to Arsenal | £18.21m
Danny Welbeck | Man United to Arsenal | £18m
Pepe, Arsenal's biggest ever signing, struggled during his first season at the club. He still has time to justify his price tag, though.
Torreira failed to become a mainstay in the team before his summer departure.
Chambers has failed to fulfill his potential, while injuries Welbeck's time at the club was filled with injuries.
Shkodran Mustafi | Valencia to Arsenal | £36.9m
Henrikh Mkhitaryan | Man United to Arsenal | £30.6m
Lucas Perez | Deportivo to Arsenal | £18m
Mustafi has made error after error at Arsenal. It's amazing how he's still at the club.
Mkhitaryan managed jut nine goals in 58 games for the club.
Perez only made 11 Premier League appearances for the club, scoring once.
Time will tell:
Thomas Partey | Atletico to Arsenal | £45m
William Saliba | Saint-Etienne to Arsenal | £27m
Gabriel | Lille to Arsenal | £23.4m
You can't judge these signings just yet.
Partey will get his Arsenal career underway on Saturday, where he's likely to feature against Man City.
Saliba is still young and is yet to establish himself in the first-team, while early indications suggest Gabriel will be a great signing.
