He also accepted "full blame" for Arsenal's Champions League exit at the hands of Barcelona.
The Gunners had Robin van Persie controversially sent off as they were knocked out of Europe by the Spanish giants for the second successive season, with a 3-1 reverse meaning a 4-3 aggregate exit.
The Dutchman was a shock inclusion for Arsenal, who led 2-1 from the first leg, having
recovered quicker than expected from the knee injury he sustained in the Carling Cup final.
However, moments after an own goal from Sergio Busquets had cancelled out Lionel Messi's fine opener following a terrible mistake by Fabregas, van Persie was dismissed by Swiss referee Massimo Busacca.
