Arsene Wenger has said he is "ready to buy players" after the Arsenal boss received criticism for losing this weekend's match against Aston Villa and was accused of being unwilling to spend on new players.
Mr Wenger issued this letter in response to fans:
We were all very disappointed. We want our fans to be happy. When you don't achieve that, you feel absolutely sorry and really disappointed.
In terms of transfers, we were on the market before the game and we are on the market after the game. But I have to look at the solution at the start of the game. Could we have won the game with the players we have? I say yes.
We take our work seriously and believe me, we analyse every single player in the world. We work 24 hours a day for that. When we make decisions, we take it seriously. People try to think we do not want to spend. We want to. We are ready to buy players.
