Alan Shearer says that Tripper has to start for England in their World Cup opener against Iran.

Shearer described him as England's "most in form defender", as the 32-year-old helpedNewcastle to third in the premier league.

If he plays, it's about where he plays for England. Shearer said that he could play left-back, right-back, and right wing-back.

On November 21, England will begin their campaign in the Persian Gulf.

Trippier helped set up one of his side's goals in the win at Saints.

As a result of Trent Alexander-Arnold's loss of form and injuries to Kyle Walker and Reece James, there is a debate over whether or not to pick the right-back in England's squad for the World Cup.

With Ben Chilwell out of the tournament, there is a problem at left-back for England.

Tripper started England's Euro 2020 final defeat to Italy at right wing-back, a position he scored from in the World Cup semi-Final defeat to Croatia.

Trippier played at left-back for England against Germany and Italy in the Nations League.

"If you want someone who is a very good defender, he is it, if you want someone who will create chances he is also it and he is also a great leader," said Shearer.

He has been a game-changing player for the team. He's been great. Under pressure, he is calm and doesn't panic. His game has been great.

It was in front of the England manager. He has to start because England has had a lot of problems.

Gary is not sure if England will be able to trust Alexander-Arnold in the World Cup.

Speaking after the Spurs win, the former Manchester United full-back said: "I can't see how Trent Alexander-Arnold could play for England in a World Cup game."

"I want this player to be the greatest right-back of all time because he's got the ability to do that, but today at times he looked like he could cost the club a lot."

He does things that aren't right. In a World Cup, there would have been a penalty against him and he's given a goal away.

I don't think he's going to trust him in a knockout game. Four brilliant right-backs could also leave.
