Liverpool manager Jurgen Klopp thought referee Stuart Attwell could have protected his players more from some tough Burnley challenges as Joe Gomez went off injured during their 3-1 win at Turf Moor.
Reds defender Joe Gomez was carried off on a stretcher in the first half and will have a scan on an ankle injury on Thursday with Klopp admitting the problem is "probably not only a little bit".
Klopp was expecting the Clarets, who have not won since September and are stuck in the bottom three, to be physical but believed his players should have been afforded more care.
"I'm pretty sure I don't make a lot of friends, but that's not my job," said the Reds boss.
"I said after the first challenge, I don't know who did it, a sliding tackle from six/seven yards, getting the ball, everybody likes it, I said to the ref 'it's no foul but please tell them you cannot do that'.
"Nobody can judge that. You get the ball, nice, but it's like bowling because you get the player as well. It happened four or five times, everybody likes it, but Joe is injured, and probably not only a little bit.
Gomez ankle injury a big blow
"We don't know (how bad) at the moment, we sent him home so we have to see, but it's his ankle yes.
"They wanted to be aggressive. Aggression is a part of football. You try something and you need someone to say 'be careful'.
"There were a lot of situations, challenges. There was nothing to say 'wow, too much', they were normal challenges. But with six or seven yards and then (slide) these times are over. They are over.
"We all want to win football games, and there are different ways of doing it. Somebody has to tell you to stop doing it, make two more steps and make a normal challenge.
"The boy with the ball is a bit unlucky because what can happen is what happened to Joe Gomez. I think the referee has to make sure that things like this don't happen constantly.
"It's not how it should be. Let's play football."
Dyche happy with approach
Burnley boss Sean Dyche was happy with what he saw from his side, which he thinks was an improvement on recent weeks.
And he had no qualms about the approach they took.
"I thought there were some excellent challenges tonight. I thought some of the timing of the challenges were superb tonight. That's part of that front-foot mentality," he said.
"You've got to win the ball, you've got to challenge against these boys. You've got to put a marker on the game - not only with good tackles, but also with good play.
"I thought we were effective. We mixed it. Not effective enough, don't get me wrong. But we've got to get back to being 'us'.
"The shape was really good tonight, the energy and endeavour and also the will to win because that was there right the way through the last breath."
Jack Cork gave Burnley the lead early in the second half before Liverpool hit back with goals from James Milner, Roberto Firmino and Xherdan Shaqiri.
"Reacting like we did at a tough place like Turf Moor, that's special," added Klopp, whose gamble in making seven changes and resting Mohamed Salah and Firmino with Sadio Mane out injured paid off.
"We wanted to change when we were 1-0 down and we changed at 1-1 because it was clear, we had to try and win the game.
"We controlled the game in a lot of moments. Second half, perfect reaction and really happy with three points."
