Former Chelsea boss Jose Mourinho believes he is no longer lucky at Stamford Bridge prior to bringing his Manchester United side to the Blues on Sunday.

Mourinho did not lose a Premier League game at Stamford Bridge during his first spell at the club, but finally tasted defeat when Sunderland beat the Blues 2-1 towards the end of his first season back at the club in April 2014.

The 53-year-old will now return to Chelsea on Sunday for the first time since being sacked by the Blues and, ahead of the game, Mourinho has admitted he doesn't feel lucky at Stamford Bridge anymore.

"When I played at Stamford Bridge with [Inter] Milan, before that match, I had never lost at Stamford Bridge [as Chelsea manager)," Mourinho said.

"I had that home record, which is still in the Guinness records.

"Now, I've lost a few matches at the Bridge. Last season, I lost two or three matches at the Bridge, so I cannot use the same words because now I have lost there."
