Released Houston Dynamo goalkeeper Tony Caig says the next five years are critical for MLS. The former Newcastle United keeper explained: "Culturally, we are more different to Americans than I could ever have imagined, and the dressing room mentality is totally different.

"To the 28 players in a squad, it's all about the team and being in it together. The players are so professional. They never complain if they get subbed, they're never shouting their mouth off in the press if they aren't getting a game and, if they have issues with a manager, it's never discussed in the dressing room.

"Salaries are capped and they're also made public, which makes the dressing room more content. A player can't go into the manager and demand more money because once the budget is spent, it's spent, and managers have to account for every last dollar.

"There is, of course, what's known as the 'Beckham rule' where two players can be outside of the wage cap, but their additional wages are paid through sponsorship.

"The American game is definitely losing its Mickey Mouse tag but the next five years will be vital for the MLS. If they can get away from the gimmicky stuff and loosen the salary cap, America will attract more top British players in their twenties.

"I think in five years' time it will be a serious league that British players will want to force their way into."
