It was really nice to see less known actors in the roles. I'm personally sick and tired of the same little old crowd always getting parts in everything. It's a fantastic mixture when you can get an actor who is well known in Romania (Marcel Iures) but relatively unknown in the rest of the world and Kuno Becker (again known in Latin America but unknown to everyone else) and put them in a British film with a U.S. actor (Alessandro Nivola) along with British actors. Really clever, nice ethnic mix and an unusual one--less predictable than the usual casting that goes on out there--kinda opens the pool of actors that we're currently exposed to all the time.
A lot of people are complaining about the football (soccer) aspects of the movie saying that it's not real, etc. But I think they're failing to see that the movie is not about the sport itself (although I think there's a fair amount of that in there as well) as much as it is about the people who play it and some of the backstage politics that are linked with it. I thought these were shown tactfully and were just enough as they were coupled with the human factor --the lives of the players, their loves, their hates, competitive spirit, etc.
What was good about having a Latino as a protagonist in the film is that it shows the wider scope of fans football has. It is not only popular in Europe but in Latin America as well. The film could have easily gone down the eurocentric route of making the story about a European case, but this made it a bit more unusual and interesting. Since Santiago was an illegal immigrant who obviously took the great risk to come to the States and didn't really have much going for him here (as is the case for most illegal immigrants anyway and is becoming more and more true with the newer policies being undertaken here) his risk of going to England to try his luck there is completely plausible to me. I have actually seen similar things tried by other Latinos going to Europe to see if their luck is better there than here for obtaining residence, etc.
Some people may feel that the portrayal of the Latino family was stereotypical, but on the whole, I thought it was positive with the characters being honest and working hard for a living rather than being common hoodlums as they are sadly put forth in many films. Santiago was shown to be a modest young man who is not too full of himself and a generally likable character.
