No safety net for wenger now.
Cup victories have kept the fans on board dispite awful league + CL showings, but now thats gone.. if he cant seccure the league (unlikely) or progress in the CL (unthinkable) then he just just respectfully depart, to a round of aplause and thanks in the summer, and leave the post for a new boss with some new ideas.
He can still leave knowing the club is not ****ed, as long as he gets top4 this season, but he should go now, before we regress further and that begins to look unlikely.
