I mean, it is. To say he was seriously poor and massively contributed to the situation is not even worth debating with.
He took over a side in freefall, he took over a side with players that don't suit his style, he took over a side that had been gutted of it's main creative players (Gylfi, Digne and James), he took over at the end of the transfer window due to the tardiness of our board, he took over when we had an injury crises to key players at the club. So many things stacked against him and he still navigated and got us to safety with a game to spare. He had to tactically change many times through the season and showed he was capable of doing so, he managed to get players on side and the fans on side. Saying he doesn't have a defined style of play is odd too, he does but a lot of our players don't suit it so he was forced to use tactics which did and they worked. If we don't get players in that suit his style I'd feel sorry for him as he will have a rough time but that's obvious. Klopp didn't go into Liverpool and make them a title winning side straight away because the players there didn't suit his style so he had to wait a couple of years until he had a squad that did.
