Alexander-Arnold has made headlines for the wrong reasons this season as his defensive qualities have come into question.
The England right-back was not included in England’s Nations League match-day squad against Germany on Monday night, according to BBC Sport.
He also did not play a part against Italy last week as Southgate’s side lost 1-0 to Italy at San Siro.
“I think he has got some deficiencies when it comes to defending, but what he gives going forward far outweighs that. In saying that, I think to win in football, you have to start a game believing you are going to play the very best of what team you are playing against,” Souness told talkSPORT.
So in that sense, you may start with a better defender, but you have got to involve Trent in your World Cup squad.”
