Manchester United breathed fresh life into the Premier League title race with a 2-0 win against leaders Chelsea at Old Trafford on Sunday afternoon.
Victory also lifted United to within four points of fourth-place Manchester City, on whom they have a game in hand, ahead of the derby at the Etihad Stadium on April 27.
"We were tactically very good and the players did an incredible job", Mourinho, who pointed to the United badge as he walked off the pitch, told Sky Sports.
At one point, Chelsea held an opportunity to win the league by a record margin, and set the total season points record.
"From a personal point of view, thinking about just about me and my work, [what made me most happy] was being totally convinced that we would be playing the FA Cup semi-final this weekend if we played Stamford Bridge with 11 men". If one day we are in the Europa League and in the Premier League the distance is too big then we have to prioritise and nobody can criticise us if we do it in a different way in the last matches of the league.
Chelsea produced possibly its sloppiest display of the past seven months, with the leaders not helped by left wing-back Marcos Alonso pulling out of the match during the warm-up as he struggled with the effects of a virus.

This can be an essential outcome but nothing has been valued and we ought to value our principles, like since first of the season. Tuchel has become more than a coach to his players in the last few days, reaching out to them on an emotional level.
Manchester United deserved the victory though as they dominated possession for much of the match, with Chelsea fighting back later.
Chelsea were furious Herrera was not penalised for a handball when he intercepted Nemanja Matic's pass prior to setting up Rashford, but he feels his action was not deliberate, meaning the right call was made.
With Chelsea striker Diego Costa spending more time provoking his opponents than taking shots at goal, David de Gea was a virtual spectator between the posts for United.
