Uncapped 19-year-old Liverpool defender Trent Alexander-Arnold has been named in England’s 23-man squad for 2018 World Cup.
Defender Gary Cahill has been recalled, and goalkeeper Joe Hart and midfielder Jack Wilshere have not been included.
England start their Group G campaign against Tunisia on 18 June, before matches against Panama and Belgium.
“I believe this is a squad we can be excited about,” Southgate said.
“It is a young group but with some really important senior players, so I feel the balance of the squad is good, both in terms of its experience, its character and also the positional balance.”
