If we don't replace the players departing with top quality signings, then yes it will definitely be a crisis. Unfortunately, Wenger's peformance in the transfer market in the last few seasons has been abysmal, so I don't have high hopes that he'll get things right this summer.

Ultimately, all this is not surprising when we have a board and manager who put profits before success on the pitch. They are like parasites, leeching from the fans but giving very little back in return apart from empty platitudes.
