England made short work of Wales on Thursday night with a 3-0 friendly win featuring a trio of Three Lions players scoring their first goals for the senior team.
England doubled their lead shortly after the restart when Conor Coady ghosted in at the back post to sweep home from a set piece, before Danny Ings opened his Three Lions account 10 minutes later from a Tyrone Mings assist.
Both teams had several players missing from their squads for the first international held at Wembley without supporters.
Tammy Abraham, Ben Chilwell, Jadon Sancho, Phil Foden and Mason Greenwood all missed the match after they breached COVID-19 protocol regulations.
"I thought the players did very well," Southgate said. "It's so difficult for a new team to come together without much experience, it was not fluid at the start but we got more and more into the game, the players saw the tactical problems Wales posed to us when they were pressing and I thought we finished strongly."
The England manager had particular praise for Calvert-Lewin, who has scored nine goals in six games for Everton this season.
"He had excellent presence, his runs are a threat, he presses well and he took his goal well. He's an all-round centre forward. I've always liked his general play but it's the goals that are making him another level of player," said Southgate.
