5) Arsenal – €678.54m
The Gunners have not actually sold their players for very high figures in recent years, with their highest player sale being Alex Oxlade-Chamberlain (€38m) to Liverpool in 2017 and Marc Overmars to Barcelona all the way back in 2000.
Cesc Fabregas was the third-most high profile, costing Barca €34m in 2011. It appears they have very much sold players in quantity rather than quality over the past two decades.
