There is a debate whether Alexander-Arnold will play at fullback or in midfield during the Euros.
Whelan wrote for liverpoolfc.com: "I’m looking forward to seeing how Trent Alexander-Arnold does for England. He certainly has the quality in abundance to shine.
"I’d like to see Gareth Southgate start him in midfield. He has got other people in the squad who can play at right-back – Joe Gomez, for example.
"I’d like to see him given a run of three or four games in midfield because I thought in the friendly game against Bosnia and Herzegovina he was very good.
"We all know how good Trent’s passing range is, he sees a pass quickly. You need to get your head up in these big games, and if he can provide Harry Kane in that final third with Phil Foden running through the middle, he could give England that little edge. Trent sees that pass quicker than others.
"I’ll be keeping a close eye to see how all the Liverpool players do in the tournament.
"I’m looking forward to seeing how Dominik Szoboszlai does for Hungary – their clash with Switzerland is the first game I will be covering.
"The Netherlands have also got a good chance with our captain Virgil van Dijk, Cody Gakpo and Ryan Gravenberch.
"I think this is going to be a really exciting tournament."
