Alexander-Arnold has rotated in and out of the team at right-back this season, mainly allowing Joe Gomez the odd rest.
But he was thrust back into the XI last time out due to Gomez’s injury and is likely to continue in the side against Southampton on Sunday.
The manager has spoken about the gradual improvement of the academy graduate, praising his technical ability and the search for consistency of a young player.
“It’s good for him that he doesn’t have to play every week,” Klopp said in his press conference.
“But he improved a lot especially in training the last few months.
“He trained a little bit like a kid, ups and downs. Meanwhile it’s consistency, consistent high level, good attitude.
“The football part of the positions seems to be really easy for him, fantastic right foot, even the left is not too bad, really good crosses, football smart—it’s all good.
“But a lot to learn of course. We have the youngest two full-backs pretty much in the league.
“Now Joey’s out and it’s really good we have Trent. He developed a lot, like Joe did. Different player obviously but both can play the position and that helps us a lot.
“Hopefully he can deliver again.”
