Not sure how Tuchel is in this conversation, yeah he won the CL but so did Di Matteo and last season's victory was owed in part to Pep's standard Champions League meltdown.
He's got Chelsea playing well in the league so far but he still needs to prove it over a season. He won the league at PSG but who wouldn't, and his time at Dortmund was so-so before he fell out with the hierarchy there and was sacked.
I think this is fuelled in part by MOTD pundits spaffing all over Chelsea so far this season, and a general angst among United fans about not supporting a club who are happy to pull the trigger on their manager (thinking if we were to, it would magically transform us into Champions League winners).
Pep vs Klopp is an interesting one, I'd say Pep is the better tactician but Klopp is the better motivator - both however are far and away the best in their profession still working today. Klopp's achievements at Liverpool are more impressive as he had a much bigger rebuild job on his hands, and has dragged Liverpool up to be one of the best teams in Europe winning everything along the way.
I still think he's an astounding manager, but aside from records and style of play, Pep still hasn't achieved anything his predecessors haven't and has spent a feck ton of money vs. his competitors along the way.
But yeah, might as well have a thread asking who's the best out of Messi, Ronaldo and Mason Mount.
