Cardiff City manager Ole Gunnar Solskjaer felt common sense was lacking for Liverpool's third goal in the title contenders' 6-3 win in south Wales.
Solskjaer's side twice took the lead in the first half through Jordon Mutch and Fraizer Campbell, only for Liverpool to respond through Luis Suarez and Martin Skrtel.
Liverpool went ahead for the first time on 54 minutes when Skrtel headed home Philippe Coutinho's corner while Cardiff duo Kevin Theophile-Catherine and Mutch were off the field after receiving treatment.
However, Solskjaer is unhappy with the rule which prevented the two players coming back on to the pitch to defend the corner.
"Of course you're hurt, everyone's hurt in there," Solskjaer told Sky Sports. "I'm hurt, my pride is hurt because to concede six goals is not something you're proud of.
"We gave them a game for a while, but then at 2-2 we've got two lads off for their corner on the third goal.
"There must be a way of looking at that rule because you've got no chance to defend them.
"Where's the common sense in football? I thought football was a common sense game, but for me it's absolutely nonsense."
The result kept Cardiff three points from safety and their next two games are against fellow strugglers West Brom and Crystal Palace.
"They're huge," said Solskjaer regarding the importance of the upcoming fixtures. "We'll regroup, you go again and look at all the positives.
"You learn from them and learn from the mistakes as well, of course.
"If you look at the results around us, probably after this round of games I think maybe people would think we were in an even worse position as people would not expect us to get anything, but the other teams around us got some bad results too."
