Liverpool manager Jurgen Klopp has confirmed Trent Alexander-Arnold must have a scan on an injury scare.
The right-back went off against Aston Villa in a comprehensive Premier League win on Sunday.
Despite the great result before the international break, Klopp admitted to having concern about his defender having a scan on a hamstring injury that forced him off in the 71st minute of the game.
I don't know exactly. I asked him, he said it's [his] hamstring. 'Not too serious' is his opinion, but we obviously have to wait for the scans and then we will know more," Klopp said after the win over Villa.
"It was a top game, the best for a while, a long time. I don't know the last time we were that convincing, and we had a few good games obviously now especially the end of last season and these kinds of things. That was really good," he added on the result.
"In both departments, offensively like defensively. You cannot do one step less against this Aston Villa team, then you struggle immediately. But the early goal might have helped, I'm not sure, we don't know how the game would have looked without scoring.
"But we looked really, really good. The mix in possession between control and direction was close to perfect. That's how it felt. We could use the formation today properly, everybody wanted the ball or protected or showed or offered.
"So, it was a top game, cannot say differently. I don't know when I can say that the next time, but for today it was as good as could be, because the opponent is extremely strong and we didn't let that happen today. That's a massive compliment to my boys."
