Mark Clattenburg was one of the most respected referees of his era but certainly came across his fair share of difficult players.
The Durham-born official took charge of Premier League games for 13 years before pursuing pastures new in 2017. He's also taken centre stage at some major European events, including the Champions League final between Real Madrid and Atletico Madrid in 2016.
He oversaw the Euro 2016 final just months later at the Stade de France as Portugal overcame France. Clattenburg dealt with a host of different individuals during his career and has opened up to The Sun about the players he struggled to deal with most.
