Chelsea coach Mourinho calls referee weak, naive

Chelsea head coach Jose Mourinho launched another scathing attack against referees, this time in the European Champions League, after his team was denied a penalty in their 0-0 draw against Ukrainian football club Dynamo Kyiv.

Cesc Fabregas on Tuesday appeared to have been trapped inside the penalty area in the first-half but referee Damir Skomina waved away Chelsea's appeals and Mourinho afterwards branded the official "weak and naive".

The English Premier League (EPL) champions have dropped three points behind Group G leaders FC Porto following their stalemate draw in Ukraine and the Portuguese boss once again criticised the officials for failing to award his side.

"The referee was weak and naive. (It was a) Big penalty decision. I don't know what the goal referee awards because he doesn't make a clear decision too," Mourinho was quoted as saying by BT Sport after the match.

"When the result is 0-0 and such a penalty is not given, I think is a pivotal moment of the game," the Portuguese added.
