He should never have come back. That was always the wrong move for the club and for Lennon. Convenience is all it was! It's a tricky one in terms of whether he's still a legend. As a player I think most would say yes but as a manager I think many would now say no. Overall.....really depends what you put more value on, his time as a player or his time as a manager.
I don't think his the sort of legend we're ever going to name something after or put up a statue of put it that way. Lol.
