Mark Clattenburg enjoyed a stellar career as a referee.

The Englishman became a Premier League referee in 2004 and he would hold that title for 13 years.

He was one of the best in the business during his career, being given the task of refereeing the Euro 2016 final and the Champions League that same year.

Clattenburg had to deal with hundreds of difficult characters during his time at the top of the game.

As we all know, being a referee is not an easy job. They are given abuse aplenty and Clattenburg would have been no exception.

But who were the most difficult players he had to manage during his time as a referee?

He revealed the five worst players he had to deal with during his career in an interview with Paddy Power back in 2019.
