Fabregas after the midfielder’s stunning debut in Chelsea’s 3-1 win over Burnley on Monday night.
After three years in Barcelona, Fabregas has returned to the Barclays Premier League – and he instantly looked at home in Mourinho’s side, who looked very much like title contenders.
The Spain midfielder set up Andre Schurrle with a perfectly-weighted pass and he also had a hand in each of Chelsea’s other two goals, scored by Diego Costa and Branislav Ivanovic.
Watching the £27million signing dictate a high tempo and put in tackle after tackle, it was hard to think why Arsenal, and Manchester United in particular, passed up the opportunity to sign the 27-year-old Catalan, who was given the man of the match award for his efforts.
Afterwards Mourinho praised Fabregas for providing him with the creativity and drive that was sometimes missing from the Chelsea midfield last season.
“I think the team played very well but I agree with Cesc being the man of the match because him and (Nemanja) Matic they controlled the game,” the Chelsea manager said.
“Those two dictated the intensity of the game. They are both good brains in this team and I am happy with that because probably last season we couldn’t control the game the way we did today.
“In the last 10 years, Cesc and I were in the same league for six or seven years so I know what he can bring to this team.
“He makes the right decisions, the right intensity of the game and he brings other people in the right direction. I am really happy with him.”
