Jack Wilshere has dismissed suggestions that inexperience was a contributing factor in England's early World Cup elimination this summer.
The Three Lions suffered a group-stage exit for the first time in 56 years as an inquest begins into the perceived failure of Roy Hodgson's side in Brazil.
Although the Arsenal midfielder refutes claims that a number of his teammates were too young, Wilshere insists that England must make amends and "deliver" at Euro 2016.
"It's easy for me to stand here and say, 'we're young, we can go forward.' But if you look at Germany, they've got young players who are delivering now," he told Sky Sports News.
"Time is running out for us to say we're young anymore. I'm 22, Ross and Luke [Shaw] and Raheem [Sterling] are young players.
"They showed in this tournament what they can do. But in the next tournament, we really have to deliver."
Wilshere's solitary start in the campaign came in Tuesday's 0-0 draw with Costa Rica.
