Roy Keane insists he has never been happier at Manchester United following reports he is disgruntled and could join Celtic.
Keane is said to be annoyed at being asked to play centre-half against Chelsea on Saturday and has distanced himself from the other players.
Keane has stated he would love to play for Celtic some time before he retires and it is being suggested he could move to Parkhead as early as next summer.
However the United skipper has dismissed the reports, claiming he is perfectly content with life at Old Trafford.
Keane said: "I can reassure the fans that personally speaking I've never been happier at the club. I'm determined to turn things round."
Keane claims he is focused on helping United beat Boavista in tomorrow's Champions League game at Old Trafford.
