Leaders Chelsea remain unbeaten in the Premier League after seeing off 10-man West Bromwich Albion.
Diego Costa marked his return to full fitness with yet another Blues goal and Belgian playmaker Eden Hazard doubled the advantage.
The game was over as a contest when Baggies star Claudio Yacob was given a straight red card for a challenge on Costa midway through the first half.
"It was comfortable but I thought in the first half we played amazingly well,” Mourinho said. “In the first half we have to be 3-0, 4-0, 5-0 up. But the quality of our football was there.
"We made the pitch very wide, we created spaces in the central area, and the result should be better than 2-0.
"We are playing well."
