Juventus boss Antonio Conte turned on the ref after their Champions League defeat to Real Madrid.
Giorgio Chiellini was shown a straight red card for a foul on Cristiano Ronaldo.
"This game was certainly affected by some very, very dubious decisions, such as the Chiellini red card and a penalty on Arturo Vidal," said Conte.
"There was absolutely not an elbow, but I still have to laugh, because if that can be considered a 'clear scoring opportunity' then so is everything... I think we'd prefer a decision against us and a good performance rather than a decision in our favour and a bad performance, as it shows signs of the team's improvement."
Conte continued: "We look forward, see the glass half-full and proved that we belong on this stage. Everyone talked about a Juventus that was a disaster area, but tonight we saw a very good Juventus against one of the top contenders for the Cup.
"We didn't get hammered and if anything we threatened to punish Real Madrid. Tonight this team proved it can walk on this stage with the right tactical adjustments and at times played better than Real Madrid.
"I think this is a good boost for us to prepare the push for the final few games."
