Mark Clattenburg - the best referee in the world

n 2008, Clattenburg was suspended following an investigation into allegations he owed £60,000 as a result of a failed business venture, and he later had his elite referee status revoked.

However, at an appeal in February 2009, his punishment was reduced to an eight-month suspension, backdated to August 2008.

In October 2014, he was dropped from officiating for two breaches of protocol - speaking on the phone with then-Crystal Palace boss Neil Warnock, before leaving a ground alone to drive to an Ed Sheeran concert.

PGMOL says officials must travel to and from the ground together for integrity and security.

And last summer he got two tattoos to commemorate refereeing the Euro 2016 and Champions League finals, and the Guardian reported he had a car with the registration plate: 'C19TTS'.

In an interview with Associated Press in December, he said he did not understand why "people see [the tattoos] as a negative thing", adding: "I'm proud of what I've done."
