Trent Alexander-Arnold, Ben White, Ben Godfrey and Aaron Ramsdale have all been named in England’s provisional 33-man squad for Euro 2020, but Eric Dier misses out.
There is a first senior call-up for Brighton centre-back White and Everton defender Godfrey, while Sheffield United goalkeeper Ramsdale joins uncapped Sam Johnstone in the squad as Nick Pope misses out through injury.
Southgate has named a 33-man group that will be trimmed down to 26 players on June 1, allowing him to include injury doubts such as Harry Maguire, Jordan Henderson and Kalvin Phillips.
Tottenham’s Eric Dier misses out on the Euro 2020 squad, but Alexander-Arnold returns to the group alongside fellow right-backs Reece James, Kieran Trippier and Kyle Walker.
Bukayo Saka, Ollie Watkins, Mason Greenwood and 17-year-old Jude Bellingham are among the others to get the nod.
Jesse Lingard is in the expanded squad after his impressive form for West Ham since joining on loan from Manchester United in January, but there is no space for Leeds United’s Patrick Bamford, who scored 17 Premier League goals this season, or Southampton’s Danny Ings.
England face warm-up friendlies against Austria on June 2 and Romania on June 6, before kicking off their tournament against Croatia on June 13.
Speaking about his decision to name a 33-man squad, Southgate explained: “Really I think our situation is more complicated than any other country at the moment.
“Of this 33, 12 are still to play in European finals this week so we were always going to need some additional players for the first part of our camp.
“Add into that we have injuries at various stages, there are a couple we have very little information about and a couple who are back into training and matches in Jordan Henderson and Jack Grealish but not training consistently.
“We felt that more time is going to help us make better decisions.
“I’ve always said my preference would be to name the squad as a clean 26, we did that in Russia and we had standby players who knew their roles and that’s always a preferable situation.
“But we haven’t got an ideal hand of cards this time and there are a lot of unknowns and I think information and evidence is really important when you’re making decisions, we’ll have more in the next seven days.”
