Gareth Southgate is already struggling to pack all of England's talent into one squad. 

The Three Lions boss has just months to work out which 23 men he takes to Euro 2020. 

The Premier League is, of course, brimming with young talent right now. Naturally, that means some unfortunate players are going to miss out. 

Looking further ahead to the next European Championships after that, England could well have the same problem. 

GIVEMESPORT have decided to take a look at how the national side could line up in five years' time when the next generation have really come of age. 

One question is whether Southgate himself will still be in charge. By then, he'd already have led England through two World Cups and Euro 2020.

It's rare for the FA to keep hold of a manager that long. You have to go all the way back to Sir Bobby Robson's reign of 1982-1990 to find a coach at the helm for eight years. 

But without further ado, let's look at England's potential 23-man squad. 

The 23-man squad

Goalkeepers: Dean Henderson, Angus Gunn, Jordan Pickford, 

Defenders: Trent Alexander-Arnold, Aaron Wan-Bissaka, John Stones, Harry Maguire, Fikayo Tomori, Ryan Sessegnon, Ben Chilwell

Midfielders: Mason Mount, Phil Foden, Harvey Elliott, Harry Winks, Declan Rice, James Maddison

Forwards: Harry Kane, Callum Hudson-Odoi, Raheem Sterling, Tammy Abraham, Marcus Rashford, Mason Greenwood, Jadon Sancho

The starting XI

Whittling that down to a starting XI is going to be extraordinarily tough. Now, it's a game of opinions, and many fans will no doubt be divided on who should start. 

Even in five years' time, Harry Kane will likely still be the first name on the team sheet. By then, he should have eclipsed Wayne Rooney's record of 53 goals (he's currently on 31, ahead of the qualifier against Kosovo) and become England's all-time leading goalscorer. 

It's hard to envisage Trent Alexander-Arnold declining either. The Liverpool full-back is just 21 years old but he's already won the Champions League and has been nominated for the Ballon d'Or. 

On the other side, we've Ben Chilwell. Three assists in the first half against Montenegro suggest it's the Leicester defender, not Ryan Sessegnon, who has been a little stop-start in the last 18 months due to injury, who'll be first-choice at left-back.  

Behind them - and this is a bold call - Sheffield United's Dean Henderson might just have what it takes to displace Jordan Pickford, who has made quite a few howlers at Everton. The Blades stopper has only let in nine goals in 12 games. 

There are other debates to be had, too. Will Mason Greenwood, Manchester United's youngest ever goalscorer in European competition, continue his upwards trajectory?

And will Liverpool's 16-year-old winger Harvey Elliott make it into the first team? Big things are certainly expected of him. 

Chelsea duo Mason Mount and Callum Hudson-Odoi may also feel aggrieved not to make it into this XI. But it's all opinions, etc. etc. 

Honourable mentions

Naturally, honourable mentions go to: 

Lloyd Kelly, Reece James, Rhian Brewster, Joe Gomez, Oliver Skipp, Dele Alli, Lewis Cook, Angel Gomes, Joe Willock, Eddie Nketiah

Whoever is managing England will have some tough phone calls to make to those who don't make the squad.
