The Blues boss hit out at Hammers counterpart Sam Allardyce after a frustrating encounter at Stamford Bridge in January.
But Mourinho has now backtracked on those comments.
Asked about his claims, he said: “Yeah, stupid, silly words.
“Last season I had a couple of words about them. Not about the way they played, about the way they started wasting time after two minutes of the game, which I don’t like.
“But I respect him as a coach. As a person he is a very good guy but as a coach he has a beautiful career.
“I’m happy that he’s doing well with West Ham. I think he deserves respect. He has my respect.”
If Allardyce wants to keep the matter alive, he might point to Chelsea’s win at Liverpool in April as an example of a team wasting time after two minutes of a match.
