That’s the verdict of former Chelsea and Tottenham SBOBET player turned radio pundit Jason Cundy.
The 20-year-old Liverpool ace was named man of the match after an outstanding display against Brazil.
He helped snuff out the heat of Gabriel Jesus, Philippe Coutinho and Neymar during Tuesday night's goalless draw at Wembley.
Fellow centre-backs Harry Maguire and John Stones, 24 and 23 respectively, also impressed at the back.
And Cundy believes it leaves Gareth Southgate with little choice but to ditch the old guard from his 2018 World Cup plans.
"One thing that I really am excited about is how many more years some of these young players have ahead of them," Cundy told talkSPORT.
"Joe Gomez put in the sort of performance [against Brazil] that I think ends Gary Cahill's international career, ends Jones' international career and ends Smalling's international career.
"I think that performance there tells me he's the future and that back three SBOBET tonight were outstanding - Gomez, Stones and Harry Maguire."
Gomez lost 15 months of his fledgling career to a rapture anterior cruciate ligament injury sustained in October 2015.
But he looks to have fully recovered and sure played himself into first-team contention in Jurgen Clop’s Liverpool side.
“It was tough at times,” he said in relation to his long recovery process. “There were phases when I felt like everything was against me.
“But I always believed I would come back. I am thankful SBOBET that I came through to it and that it’s behind me now.
Liverpool face Southampton at Anfield on Saturday in the Premier League (3.00pm).
