Liverpool manager, Jurgen Klopp has said he was not impressed with the penalty decision awarded to Chelsea during Wednesday night's UEFA Super Cup.
But the German reserved praise for the all-female officiating team.
Stephanie Frappart, 35, made history by becoming the first woman to take charge of a major men's European match alongside her assistants, Manuela Nicolosi and Michelle O'Neill.
Tammy Abraham went down under a challenge from Adrian in the first half of extra time and Frappart swiftly pointed to the spot before brief consultation with VAR.
Klopp felt aggrieved at the penalty decision but was full of praise for the officials who performed superbly on the night.
He then told reporters after the game: "I told the ref team after the game that if we would have played like they whistled, we would have won 6-0. That was my absolute opinion.
"They played a brilliant game. I told her as well that I am not happy with the penalty decision because I'm still not sure that it was a penalty, but it's not important anymore. They were really good.
"Whatever you could have thought before the game, there was pressure on them like hell with an historic moment.
"Staying by yourself, staying calm and do what you have to do, decide very important things in a very difficult and intense game, I couldn't have more respect, to be honest. It was a really brilliant performance."
Liverpool went on to win 5-4 in the shoot-out.
