how old can you be to play for england u21
England national under-21 football team This team is for English players aged under 21 at the start of the calendar year in which a two-year European Under-21 Football Championship campaign begins, so some players can remain with the squad until the age of 23. As long as they are eligible, players can play for England at any level, making it possible to play for the U21s, senior side, and again for the U21s, as Jack Butland, Harry Kane, Calum Chambers and John Stones have done recently. It is also possible to play for one country at youth level and another at senior level (providing the player is eligible).
2017–18 FA Cup The third round match between Brighton & Hove Albion and Crystal Palace on 8 January 2018 was the first competitive game in England where video assistant referee (VAR) technology was available, although it was not used.[2]
