Three new faces called up to England squad
Southgate, who extended his contract with the national team until 2022 earlier today, has named his 25-man squad for the upcoming fixtures against Croatia and Spain.
James Maddison, Mason Mount and Jadon Sancho have all be included with the senior squad for the first time in their career.
Jadon Sancho, who was representing England at the FIFA U17 World Cup Finals in India this time last year, has impressed in the Champions League at Borussia Dortmund.
Ross Barkley returns to the fold after a two-year absence, while Nathaniel Chalobah and Harry Winks are recalled following their respective recoveries from long-term injuries
When asked about the three new additions during his media briefing Southgate told reporters that, "They're exciting young players and it's a great opportunity for us to look at them.
"With young players, you never know what they're capable of until you give them their opportunity.
"It may be a bit early for them, but they're having big impacts in important matches."
England play Croatia on October 12 and Spain in Sevilla on October 15, with both games counting towards England's UEFA Nations League group.
The 'Three Lions' did not get off to the best of starts in the competition, losing 1-2 to 'La Furia Roja' at Wembley.
