Former Premier League referee Mark Clattenburg has admitted to having a difficult relationship with Jose Mourinho the second time the Portuguese managed in the Premier League.
Clattenburg, 43, refereed in the top flight for 12 seasons before leaving English football in February 2017 to take up a role with the Saudi Arabian Football Federation.
Regarded as one of the best referees in the world, Clattenburg took charge of high-stakes matches including the Champions League final, FA Cup final and the European Championship final in 2016.
And in an exclusive interview with talkSPORT, Clattenburg revealed that his relationship with Mourinho grew more strained as time passed.
He referred to a game between Chelsea and Stoke where Mourinho led Clattenburg to believe that he made a wrong decision after the final whistle, but replays showed Clattenburg was correct
And Clattenburg suggested the ex-Blues boss did this fully in the knowledge that the right decision was made.
He said: “When he first came to England, Jose Mourinho was special. He had time for everyone, you could have a conversation with him about football, about life, about anything.
“But when he came back things were different. He had a difficult relationship with me and refereeing.
“I remember this game at Stoke, where he came in 30 minutes afterwards as usual. He was adamant I had missed a penalty decision and that he’d seen it on the video.
“I then watched the video and the ball quite clearly hit Ryan Shawcross’ chest instead of his hand.
“I don’t know what video he’d seen or if he was just playing mind games but I had to drive 200 miles home thinking I had made another mistake which eats away at you.
“When I got home and found I hadn’t made the mistake I thought ‘why?’
“Being a referee is sometimes a tough job but you don’t need the other side of it where they play mind games to try and get into your head because there’s no need for it. Refereeing is a tough life at times.”
