Liverpool star Trent Alexander-Arnold has not been included in England's squad ahead of Euro 2020.
The Three Lions manager selected Chelsea right-back Reece James, instead.
“I don't think he's [Trent Alexander-Arnold] played at the level he's been at the last few years. Reece James and Kieran [Trippier] are in exceptional form,” revealed Southgate.
“We have other players in the league who are also playing well in that position – Cash at Aston Villa, Ayling at Leeds – and we've got two very good right-backs in the Under-21s. It's a remarkable position of strength and what I said to Trent earlier today was I have made the same call to Kyle and Kieran in the past.
“Their response was a good one. They took up the challenge and found themselves back in the squad. Trent is a super talent and I'm certain will play a big part in the future. He misses out this time but we could quite conceivably be sitting here in the summer and he's with us.”
What's going on with Alexander-Arnold?
While the decision to exclude Alexander-Arnold from England's team for World Cup qualifiers appears harsh, the Liverpool star has been in a slump for his club side. But so too has Klopp's side, sitting 6th in the Premier League table.
A mainstay in the England line-up since the 2018 World Cup, Alexander-Arnold has won four major honors including a Champions League and Premier League trophy at the age of 22.
The generational talent may just be experiencing a dip in form. The Reds' ongoing injuries at the center-back positions have perhaps exposed Alexander-Arnold defensive capabilities.
England is lucky enough to be rich in full-backing talent.
Who's in England squad?
Ollie Watkins and Sam Johnstone receive their first call-ups to the quad. BVB starlet Jude Bellingham also gets the call-up but may face restrictions due to Covid-19 traveling rules in Germany.
Jesse Lingard has been recalled to the team, with Southgate saying that “we know he can perform at this level.”
