United enjoyed over 70 per cent possession at Stamford Bridge but were put to the sword by Eden Hazard's first-half strike as the Blues opened up a 10-point lead at the top of the Premier League table.
When asked by Sky Sports if the possession statistics bothered him, Mourinho replied: "No, never, it could be 99%. When you decide to play the game strategically you don’t care about stats, you care just about the points.
"We played this game strategically. We were very well prepared and were able to make some very important players disappear, nobody saw them, we had also a big heart to fight, people very focused on their jobs.
"All the defensive set-pieces were in our pockets. I know what people can think but football is talent and strategically it is also very important. I love [winning like that]."
