Virgil van Dijk hit out at Sevilla hatchet-man Joris Gnagnon following Liverpool's bad-tempered friendly loss in Boston.
The Reds defender was furious with Gnagnon's shocking second-half kick on youngster Yasser Larouci, which saw the left-back stretchered off during the 2-1 defeat.
Van Dijk took issue with Gnagnon, confronting him at the final whistle, before Larouci left Fenway Park on crutches.
Gnagnon took to Twitter to issue an apology for his actions, while Sevilla also sent a message wishing Larouci a full and speedy recovery.
However Van Dijk, speaking to Goal afterwards, made clear his displeasure.
“I saw it from the side, it’s not nice,” he said. “Especially when it happens against such a young guy who is playing pretty well this season. I think it says something about him.
“You have to just deal with it, but obviously you don’t want to have injuries in a game like this.
"You want to get fit, you want to get back to your best. Obviously everyone wants to win the game, but the most important thing is to get fit.
"Hopefully for Yasser it is not that bad.”
James Milner branded Gnagnon a “disgrace” after the incident at Fenway Park on Sunday night.
Milner said: “There were some disgraceful tackles, we know it was a friendly but you don't see many red cards in a friendly.
“If you want to foul, pull a shirt. Don't take a young lad by the knee. Seeing it again it is a disgrace.”
Reds boss Jurgen Klopp was diplomatic however - despite having been visibly furious on the touchline.
"It is much too early in the season to create headlines by saying the things I think about the situation. It looks like he was lucky but we have to wait a little bit.
“He couldn’t keep on playing but in the dressing room he looks OK. Harry got a knock on his cheekbone and his eye so not too cool.
"He should be ok as well. That is the situation."
