Chelsea boss Jose Mourinho has branded Slovenian referee Damir Skomina "weak and naive" after his side's 0-0 draw with Dynamo Kiev on Tuesday night.

Mourinho felt that his side should have been awarded a penalty after a foul on Cesc Fabregas in the first half and speaking after the match he echoed the words Arsene Wenger used against referee Mike Dean several weeks ago, which went unpunished.

Mourinho said: "The referee was weak and naive. It was a big penalty. I still do not understand what official behind the goal does. Because he doesn't make a clear decision.

"When the result is zero-zero and such a penalty is not given it's a crucial moment in the game."
