The Blues have been transformed since Tuchel's arrival in February, reaching both the FA Cup and Champions League finals.
"We have to win football games next year," said Klopp, via Goal. "And City is not the only challenge. Chelsea looks, I said when Thomas arrived there: this squad is a present. And together with Thomas, obviously it works out pretty well. If you look at the squad, they can make 11 changes and you think, 'Oops, that's a proper team.'
"They will go for it next year definitely, they will not get worse. That's a fact. United are in a good way. So, it's not about who is far away or whatever. It means just you have to win your own football games and that's possible."
