Jurgen Klopp was not impressed with the penalty decision awarded to Chelsea in Wednesday night's UEFA Super Cup - but heaped praise on 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 referee 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 said: "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."
Olivier Giroud 's first half opener was cancelled out by Sadio Mane early in the second which took the sides into extra-time.
Mane put Liverpool ahead in the 95th minute only for Jorginho to level from the spot, forcing the shootout which the Reds went on to win.
Both sides return to Premier League action this weekend with Liverpool travelling to Southampton on Saturday while Chelsea host Leicester City on Sunday.
