Chelsea boss Jose Mourinho was delighted with the manner of their 2-0 win over West Bromwich Albion.
Goals from Diego Costa and Eden Hazard earned the points for the Blues.
Mourinho used a host of superlatives to describe Chelsea's first-half performance, but they noticeably tailed off after the break despite West Brom being reduced to 10 men.
The Blues manager wanted more goals from his side but understood his side's intensity dropping, despite looking increasingly irritated on the touchline.
"Yeah, but I am always annoyed," he said with a smile. "I am always annoyed and the players know that.
"But sometimes I have to realise that there are reasons for things, like national team matches, people having to play two matches in a row, coming back, travel. We didn't train properly.
"The players know that they have a marathon of matches, they know they play in Germany on Tuesday, so the intensity went down.
"They knew that the points were not at risk. The objective was to win the three points and I think they also knew that because we spoke about at it at half-time that the first half was absolutely beautiful.
"Many, many times I am upset, but I think not today."
