Wenger has been offered a new 2 year contract, when his current one ends. Uncertainty over his future seems to be affecting the way Arsenal plays. He should just make up his mind and say whether he accepts the contract or he is moving on.
Agreed, Asenal should have new coach to move up. I think Wenger's strategy doesn't effect to arsenal if they want get something big like EPL or UCL Throphy. With new coach of course Arsenal will playing with new strategy and may be that will be better. Im not Arsenal fans but sad to see Arsenal not get EPL trophy for long time like this.
