If Trent Alexander-Arnold works on his defense, he can be one of the best right-backs of all time.
Alexander-Arnold has struggled for form this season and has come under scrutiny.
He was dropped from the squad to face Germany for not playing against Italy.
"I've never seen a full-back in this country that can do what he can do," he said.
We will probably have the best right-back the world has ever produced if he can just work on the basics.
This is a level of full-back not seen in Brazil.
For England, he played 85 times, and for Manchester United, he played 602 times.
He said there was an "imbalance" to Alexander-Arnold's game.
After Alexander-Arnold was left out of the England team, he was defended by his boss, but he admitted there was room for improvement.
"I think Trent needs to work on his defensive skills." A few years ago, I stated that there was a lack of seriousness in his defense. It will stop him at some point in his career.
Alexander-Arnold's "all-round game" was behind that of Trippier, according to the England manager.
There is a chance that the player could be left out of the England squad for the World Cup in 2022.
This is a crucial time in his career. I don't want to do that, what does he do?
If he can have five to six weeks here just being coached, that could be the biggest positive of his career.
