Celtic manager Neil Lennon was unhappy with officials after he believed that his side should have had a penalty during Sunday's Scottish League Cup final defeat to Kilmarnock.
Anthony Stokes looked to have been fouled by Michael Nelson inside the area towards the end of the match at Hampden Park.
The incident came after Dieter van Tornhout had headed in the only goal of the game on 84 minutes.
"You've got to take your chances and we missed simple chances. We should've had a penalty," Lennon told BBC Scotland.
"It's a penalty and a sending off at a big moment in the game. I'm not saying we would've scored the penalty but I think the referee's got that one completely wrong."
The Irishman was also disappointed with his team's inability to convert their chances during the shock loss.
"We dominated the game so Kilmarnock can count themselves pretty fortunate that they've won the game," Lennon added. "And maybe that's down to a lot of luck on their part and poor finishing from us.
"I'm very disappointed for our players but we've got a league championship and a cup to win so we'll lift them again and go again."
Celtic could win the Scottish Premier League next weekend when they travel to Old Firm rivals Rangers.
