Wenger is under increasing pressure after their defeat at Brighton on Sunday.
“The FA Cup wins in recent years have been great, but the Arsenal fans demand more and that is partly due to the expectations Wenger built up in his first few years at the club.
“What has changed now is that he is nowhere near the top four this season and that has compounded the pressure, but this man has given so much to Arsenal for the last two decades and I believe he has earned the right to have one final crack at trying to save this season in the Europa League.
“The light at the end of the dark tunnel they are in at the moment is the Europa League and that could turn around the whole season. They really need to go for that now and if they can galvanise themselves for the AC Milan game on Thursday, they could do what Man United did last season and save their season by winning that competition and getting into the Champions League.
“If they win the Europa League, people can sit back at the end of the season and decide what should happen next, but the first step has to be trying to stop the rot by getting a position result in Milan on Thursday."
