Chelsea boss Jose Mourinho described his side's performance against West Bromwich Albion as quality.
The Blues extended their lead at the top of the English Premier League to seven points with second-placed Southampton to face Aston Villa away from home on Monday night.
"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. I don't remember seeing many times football of that dimension.
"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.
"We are getting the results that we deserve and I'm pleased that we did. Especially after 15 days when I have no players to work with. But it's three important points."
Striker Diego Costa was again on target for Chelsea and Mourinho says the player is making a difference after fully recovering from injury.
"It's easy to see the difference in him [Diego Costa] now, because now he can run, he can sprint, he can challenge for every duel," said the manager.
