But Mourinho maintained that the Mancunian Blues are still just one of six teams yet to prove that they can pull away from the chasing pack.
He said: "I watched the game and they were very good. No doubt about it. They bought fantastic players, they have a fantastic squad and they looked very, very good.
"When you look at the players they didn't have on the pitch, and some were not even on the bench, the squad is amazing. They are a fantastic team and an amazing squad.
"So, yes, they are big contenders. But, for me, I think we start, all six, on zero points."
