The life of a coach...

When Jose Mourinho responded to Arsene Wenger's jab that Jose was afraid of failure that was why he was playing down his Chelsea side's chances of winning the league, everyone insulted and blamed Jose.. In his word "He will
know when someone is afraid of failure because he's a specialist in failure, eight years without a trophy is failure"... Jose has since won the league and moved on to another challenge.
Why can't Arsene Wenger get a new challenge? Hasn't he proven Jose Mourinho right?
SHOULD ARSENE WENGER RESIGN OR STAY?
