Chelsea boss Jose Mourinho was left fuming at the match officials again after seeing his side play a goalless draw with Dynamos Kiev.
Chelsea had a penalty claim denied after Fabregas was brought down by Dynamos Kiev’s Serhiy Rybalka.
Speaking after the match Mourinho said, ‘The referee was weak and naive, it’s a big penalty.
‘I keep not understanding, what the goal referee does. Because (he) doesn’t make a clear decision.
‘When the result is 0-0 and such a penalty is not given it’s a crucial moment of the game. ‘I actually think the referee was very good but I think he made one mistake.
Mourinho was recently fined in the Premier League for comments made about referee’s and may now attract a similar ban from UEFA in the coming 48 hours.
