And Mourinho was gushing with praise for the Spain international, who joined from Atletico Madrid this summer, after watching his side return to the top of the Premier League.
“He produced a fantastic performance in every aspect,” said Mourinho. “I remember in the first half he was tackling [Seamus] Coleman on the edge of our box. He recovered balls, he held the ball up, and he was aggressive.
“He came face to face with Howard three times and he scored two goals. Howard made a good save in the beginning of the second half. His movement, his quality – everything was really good.”
The Chelsea boss continued: “The end of the story is that Diego is maybe the best player in the league in these first three matches.
“He is the top scorer, and he has two yellow cards: one against Burnley where he didn’t simulate, and today when everybody was chasing him to get him in trouble.”
