Barcelona midfielder Ilkay Gundogan was left disappointed after his side threw away a two-goal advantage and went down 4-1 to Paris St Germain to exit the Champions League on Tuesday.
After bagging a 3-2 win in Paris and taking a 1-0 lead with an early Raphinha goal in the quarter-final second leg, Ronald Araujo was shown a red card as PSG made a comeback to secure spot in the next round.
"Very frustrated. Very disappointed. It really felt like that we had full control of the game. Started with a one-goal lead, and then after 10-15 it just felt like we destroyed ourselves," Gundogan told TNT Sports.
"Yeah, (the red card changed the game). This is the Champions League. No matter who the opponent is, in such a tie, such an important game, going one man down so early... it's impossible, then you are out, unfortunately."
Barcelona manager Xavi Hernandez lashed out at referee Istvan Kovacs and blamed the latter for the club’s exit from UCL.
Kovacs showed red cards to Araujo and Xavi, with five Barcelona players also receiving yellow cards.
"At halftime, (the referee) didn't have such a bad attitude. I haven't seen any of the crucial actions on the replay, but it felt like he was very quick on the yellow cards for us," Gundogan said.
"In the second half, I think I should get a penalty. He clearly kicks me with his leg - if not, I can continue running. If he doesn't kick me, I don't fall. For me, that's a penalty.
"That's what I told him, to at least have a check, and he gave me a yellow card. I don't know how it looks on TV - maybe my impression is wrong."
