The Gunners received £30m when Fabregas completed his protracted move to Nou Camp in August while they also collected £24m when Nasri joined Roberto Mancini's men in the same month.
In total Arsenal gained £63m from the sale of players as figures were also boosted by Gael Clichy’s move to City and Emmanuel Eboue’s switch to Galatasaray.
Arsene Wenger has often been criticised for not investing in his team, however, in 2011 the Gunners invested £74.3m in playing staff including transfer fees and wages.
The Frenchman spent £12m bringing Alex Oxlade-Chamberlain to the Emirates from Southampton, £10.5m was spent on Gervinho while Mikel Arteta cost £10m when he moved from Everton in August.
Non-executive chairman Peter Hill-Wood told the club's official website: “We are proud of Arsenal’s record and consistency over many seasons and have the foundations in place, at every level of the Club, to ensure we remain a force in the seasons ahead."
Arsenal also brought Thierry Henry back to the club in a two-month loan spell from the New York Red Bulls after the legendary striker initially left the Gunners to join Barcelona in 2007.
Hill-Wood added: “With regard to Thierry, it was a special moment to have him back with us for his statue unveiling.
“This was only surpassed by that winning goal against Leeds United on his return to action in an Arsenal shirt. It was a truly memorable football moment from a true Arsenal servant.”
