Jose Mourinho said he felt betrayed by his players following Chelsea's 2-1 loss to Leicester City.

Mourinho also criticized the ballboys, whom he accused of being a “disgrace to the Premier League” for alleged time-wasting.

Asked whether he was 100 percent convinced that he would still be in charge for the Sunderland game, Mourinho replied: “The only thing I can say is that I want to be. I have no doubts and I think you know me well enough, three years this time, plus three years another time, that I am not afraid of a big challenge, and in this moment this is a real big challenge. I want to stay, I hope Mr Abramovich and the board want me to stay.”

Chelsea are currently in the relegation zone after winning the EPL in 14-15.

“My board, my club I don’t think it’s right that I go to them and say these players are not good, we need to spend £50 million or £100 million or whatever, I don’t think it’s fair,” he said. “We have these players and it’s with these players we have to go. The players that are not performing well, they must feel attacked in their pride and their self-esteem and they have to do everything to get results in a humble way.

“I don’t think in this moment they can feel they are top players or they can feel they are superstars. They have to look at the Leicester boys and to feel these are the stars, these are the top players. They have to look to Sunderland and Watford and say: ‘We are at the same level. I am not the superstar, I am not the player of the season, I am not the world champion, I am not the Premier League champion. At this moment, I am at your level.’”
