Jose Mourinho has distanced himself from reports that his former Porto side are guilty of bribing referees.

The Portuguese giants have found themselves caught up in a controversy over their title success in 2004.

Porto president Jorge Nuno Pinto da Costa has been accused of corruption by bribing referees in Portugal, leading for calls for Porto to be stripped of their title.

Mourinho has not been implicated in the inquiry and the Chelsea boss has rejected the suggestions that his success with Porto was helped by bribes.

"The only thing I know is my team at Porto did a fantastic job, crowned with national and international conquests," Mourinho is quoted as saying in the News of the World.

"I know what I did, the pride I have in it, the contribution I made towards those successes.

"I believe all those who took part with me are all as proud and professionally fulfilled as I am by their contribution."
