The Portuguese tactician believes with the injuries he has in his squad the two-time champions are not at their free-flowing best.
Chelsea were close to dropping points at Everton before two superb strikes from Frank Lampard and Didier Drogba gave The Blues the points.
The win moved Chelsea within two points of Manchester United, although Mourinho would have been happy being two wins away from the league leaders.
"If you can't play great music, then you must at least play some," stated Mourinho. "That is what we are doing at this moment.
"In great moments, teams play great football and score great goals. Everything rolls on. The first chance you create, you score. You go on to the pitch and everything is shining, there are flowers and blue sky.
"We are not in that situation just now. We have players injured and we are hitting the post at least twice in every game.
"If we were six points behind I would be happy. The important thing is that we are there."
