Liverpool boss Jurgen Klopp refused to speak about refereeing decisions this weekend.
The Reds had to settle for a 2-2 draw against Brighton in the Premier League on Sunday.
There was further refereeing controversy, with Brighton midfielder only receiving a yellow card for a last man foul on Dominik Szoboszlai that resulted in a penalty for Liverpool.
Afterwards Klopp said: I don't know. I don't know, I think it the foul is inside the box for a penalty it's a yellow card but if it's outside it could be red.
I don't know, don't talk to me about rules. I take what I get.
Did anybody say he should have been sent off? I trust an expert would know, I don't know."
