Goals from Diego Costa and Gary Cahill saw the Blues beat Liverpool 2-1 at Anfield on Saturday to keep their comfortable lead at the top of the table.
But following the match Mourinho spoke about the condition of Cesc Fabregas, who featured in the win despite having a hamstring injury.
The manager said: “It was a fantastic performance from the team.
“As a team and as individuals it was a great performance. The team is under control and has a big personality.
“But to be fair I must award Ramires and [Cesc] Fabregas and my medical department, they did fantastic work on them and they were fantastic to resist the problems they had.
“Fabregas may have a problem for the next match, we gambled everything on a hamstring problem and the medical department and I decided he could play.”
