Barca thought they had victory in the bag when they roared back from two goals down to grab a 3-2 lead with Raphinha's goal in the 87th minute but Inter equalised through Francesco Acerbi in added time to stay alive and then scored the winner.

Flick criticised Polish referee Szymon Marciniak who had a busy night in the semi-final, second leg at San Siro, with Inter advancing 7-6 on aggregate to face Paris St Germain or Arsenal. 

He awarded Inter a penalty after a VAR review for a challenge by Pau Cubarsi on Lautaro Martinez that he did not deem an infringement and later reversed a decision he had signalled as a spot kick for Barcelona, with Video Assistant Referee saying Henrikh Mkhitaryan's foul on Lamine Yamal was just outside the box. 

Barca's players and bench also complained about what they thought was handball inside the box by Inter defender Acerbi and a foul by fullback Denzel Dumfries on Gerard Martin in the build-up to the equaliser which took the game to extra time. 

"I don't want to talk too much about the referee, but every decision that was 50-50 went (Inter's) way," German Flick told a press conference.

"I am disappointed, but not with my team. They tried everything. It's the way it is. We are out, but next year we will try again to make the fans happy.  

"It makes me sad. My team did an excellent job. I don't like talking about the referee. I've told him what I think, but I'm not going to say it here what I've said."
