Manager Thomas Tuchel has told Trent Alexander-Arnold he needs to improve his "defensive discipline" if he is to help England to win a major tournament.
The 26-year-old has been named in the Three Lions squad for upcoming games against Andorra and Senegal, having been injured for the March camp.
The outgoing Liverpool right-back is admired for his offensive ability and is expected to complete a switch to Real Madrid this summer.
However, the German says the vulnerability he shows when defending needs to be addressed.
"I can see that sometimes he relies heavily on his offensive contributions, and gives not so much emphasis on the defensive discipline and effort," Tuchel said.
