"Mark Clattenburg has come under criticism from Juventus boss Antonio Conte, who claims the Premier League official isn't up to the "required standard".
The Serie A giants were knocked out of the Europa League at the semi-final stage by Benfica last night after an ill-fated 0-0 second leg in Turin.
Clattenburg sent off visiting defender Enzo Perez in the second-half before an angry confrontation on the touchline saw substitutes Mirko Vucinic and Lazar Markovic both shown the red card.
And
the top flight referee has today been slammed by Conte for his performance.
The Juve boss said: "I didn't appreciate either the attitude of our opponents or the referee.
"UEFA should show us more respect by sending a referee of the required standard.
"The referee allowed them to obstruct the play the whole game. Before the game he told us that he wouldn't stop play every time a player hit the floor, but that's what happened".
Not everyone in football thinks that Clattenburg is the 'best ref around'.
