You should be able to win the 2014 World Cup with the squad and players England have.
FM-wise, they have some of the best players in-game. Get the right tactic and I'm sure you can win it.
such an open ended question and sort of pointless mate.....
it depends on regen development, tactics, injuries, players like Rooney and Young would be at least 33yrs old... Wilshere would be in his prime.. Walker, Caulker, Smithies, Jones, Chamberlain etc would also be at a good age, but it also depends on how these younger players have developed...
plus you lost against Spain, not like you lost against Saudi Arabia mate
Sigh, it was a pretty stupid question.
You can win any competition you are in, that is kind of the point of the game, if there was no way of winning it, it would be pointless to play.
What I am asking is how possible is it.
Depending on the regens/state of the team you acquired when you took over, I would suggest it would be relatively easy if you have a good tactic, which I guess you will have considering you won the Euros. Although, Brazil and Argentina always seem to produce awesome regens on my saves, so I imagine they will be a bit of a challenge, but nothing overly strenuous, and far from impossible.
I suppose it also depends on the teams you draw throughout the competition, if you end up playing Scotland/Israel/Iran/Estonia on the way to a final against Poland, it would be allot easier than a run against Brazil/Argentina/Spain/Italy/France/Holland/Germany for example.
