No-one has forgotten those. They don't get MoPe off the hook. His team is more talented than Puel's Saints and has a lighter schedule. No-one is claiming Puel to be a world beater but he was a damn sight better than the clown we have in charge right now.
Why bother firing Puel if you don't bring in someone better and with a different philosophy? He sets the team up like puel did, attacks a bit like Puel did (i.e. not much) but doesn't have a clue about defense. He has to go after thus game, has to.
