How about, "I made the WRONG decisions this season and it has cost us. Again. I'm the manager, I am responsible."
Can you even imagine Wenger saying something like that? Instead, he has made 20,000 substitutions, how many have you made? Or, how many cups did you win before he arrived? Or, the fans need to change.
Yes, it is the standard responses he's rolling out. What makes him think he can get away with that at this painfully late stage in the game? Kroenke and Gazidis I suppose. He has those two where he wants them, that'll be what he means when he says there are more important considerations than the fans.
