Jose Mourinho insists he is fully behind Manchester United in the wake of Sunday's heavy loss to Chelsea.
The Red Devils were beaten 4-0 at Stamford Bridge in what was a homecoming to forget for the former Blues manager.
Following the disappointing defeat, Mourinho told MUTV that he feels sorry for the club's supporters but wanted to ensure to them that he is now all about United and has no thoughts about his old team Chelsea.
"They kept going for 90 minutes in an unbelievable way, the fans that we have all around the world they are obviously with a very bad feeling and I feel so sorry for them," Mourinho said.
"I have to apologise for that and the only thing I can say is that I am Man United 100%, not 99% and 1% for Chelsea or any other club and because of that I feel deeply the situation.
"But there is only one answer, like I was telling the players, there is only one answer - training tomorrow and we fight on."
