Roy Keane has revealed that new Manchester United boss Jose Mourinho is 'not his cup of tea'.
Mourinho officially took charge of the Red Devils on a three-year contract last week and will lead the 20-time English champions into the 2016-17 campaign.
Former Man United captain Keane, however, has said that he finds the Portuguese "really irritating".
"He is not my cup of tea. I found him really irritating when I coached against him, but that is just a personal thing," Keane told ITV Sport.
"Working at Manchester United is all about winning and his CV will tell you he is a winner. He was always going to be a good option when United didn't qualify for the Champions League. He was available, fantastic CV and it seems like a good fit, but maybe he is not for me."
Man United have finished seventh, fourth and fifth in the Premier League table since Sir Alex Ferguson departed in 2013.
