Liverpool manager Jurgen Klopp refused to criticise the rules surrounding the FA Cup despite his team's hectic fixture list.
A 0-0 draw against West Ham in the fourth round on Saturday added yet another game to Klopp and Liverpool's schedule with the replay.
"These are your rules and I think most of them are older than we are," Klopp said.
"You would say I'm crazy if I sit there, punch the air and say, 'yeah, another game – let us play five’ but I have nothing to criticise.
"There is a debate, but I come from Germany and I am coming from the outside.
"I cannot lead the community and say 'come on, let's make a 16-team league' or something like this. I love football, usually I can’t get enough of it, but sometimes it's a bit different."
Klopp said it had been a good opportunity to see what the club's younger players were capable of.
"With these young ones we have enough time to train," he said.
"Not as a team before the next match, but when we come back and we have them in our sessions. I know a lot about these guys – that's the only reason they played.
"The good thing is if we hadn't had so many injuries and so many games then we wouldn't have seen these guys, so it's positive."
