"The problem with Arsenal is not buying big stars. The problem is Wenger. Sack him, and Arsenal would be just fine..."

While the above statement from a fan of Arsenal could be considered harsh, a lot of people would find solace in it.
Sadly, while Manchester United, Chelsea and Liverpool have been linked with players coming in these past few days, Arsenal have been linked with players moving out. Cesc Fabregas remains a target for Barcelona, Manchester City, Inter Milan and even Real Madrid. Samir Nasri has failed to sign a contract and Manchester United have been hovering around. Gael Clichy continues to tickle Liverpool's fancy. But how serious Arsenal, and indeed Wenger acts to keep them would be the key.
Wenger admitted last season saw him tasking himself the most throughout his career. On evidence of the results, his best wasn't good enough.
Next season would be his chance for redemption, may be his last chance. Whether he rises up to the challenge by changing his obviously flawed philosophy, we would find out.
