I understand that Pep wanted to have some response, he can't really just keep going like this and still be saying that he is doing badly, of course we know he is doing badly, the problem is that he is not figuring out a way to get better neither.
It's been 7 games since they had a win, and lost 6 of them as well which is quite unusual for him, and something that is really looking weird for his legacy as well. Not saying that he is going to be remembered as bad or something, dude won so much, he won six premier league titles, and even a treble once with UCL as well, so his legacy is good, but for example Sir Alex Ferguson never lost 5 in a row in all 20+ years of his career, that has to be an important thing to remember.
That's not just a response it's what's happening if you watching his match since the day he started loosing till date you will find some improvement a example for the match against Tottenham after Debruyne was brought up you can see some passes but before he was brought the bid chances were not their it's just that it's a crisis that fall upon them and this is the first guardiola has lost 4 games in a row in his coaching career so I can say it's just a crisis that fall on them
