Alexander-Arnold could start his first league game for a month at Fulham on Sunday having completed 90 minutes in the Champions League against FC Midtjylland in midweek.

"It was only when I told him that I saw that it meant a lot to him,'" said Klopp. "That's cool and it will be his role in the future when other players have finished their careers here.
"He is already preparing to be the face of this club in the future – hopefully along with some others. That's really nice and when I saw how much it meant to him it made me happy. But the decision was a logical one because of the time he's been at the club."
