The Ref who Mourinho once described as "weak and naive", will officiate United's Europa League final against Ajax

Damir Skomina, an official Manchester United boss Jose Mourinho once labelled "weak and naive", will referee the Europa League final .

UEFA announced on Friday that the Slovenian will officiate the Stockholm clash between United and Ajax on May 24.

Skomina has been an international referee since 2003 and this season has officiated six matches in the Champions League - a competition in which the 40-year-old irked Mourinho in October 2015.

Following Chelsea's goalless draw at Dynamo Kiev in the group stage, and during one of his fallouts with the Football Association, the Portuguese labelled the referee "week and naive" after ignoring penalty appeals from Cesc Fabregas.

"The referee and the goal referee decide not to give (it)," Mourinho added.

"Against Porto (when Chelsea lost 2-1 in their previous group game and were denied a late penalty following a handball claim) it was a clear handball, last minute, a decision crucial for the result of the game.

"Today it was not last minute, but it was a clear penalty. I don't know. The referee didn't see it? The referee decided not to give it?"

Felix Brych will referee the Champions League final between Juventus and Real Madrid in Cardiff on June 3.
