Arsenal legend Paul Merson believes the club could rue their decision if they let manager Arsene Wenger walk at the end of the season.

There are some rumors that this season will be Wenger's last at Arsenal, especially if he is unable to win the side the Europa League.

The European trophy is the only chance for Arsenal to get back into the Champions League for next season. But Merson suggests losing Wenger could hurt Arsenal in the future.

Merson told talkSPORT: "I think he'll be a manager somewhere else.

"He'll get a job in two minutes when he leaves Arsenal. He'll want to manage again.

"I look at Arsene Wenger and football is his life. He will manage again.

"That is the problem for Arsenal. When he does go, he could come and haunt them, because wherever he goes he could go and do something special like he did at Arsenal."
