1) Champions league games are basically the best teams and who twins are the best team in Europe, right? yeah the teams go into the champions league if they win there own league or are in like 2nd,3rd and 4th in Britain but they have to then qualify
2) Whats the FA Cup? and is the UEFA Cup all about the lower tier teams? the F.A cup is a english cup that all teams take part in from non league to top teams. UEFA Cup is the few teams below those who qualify for the Champions League.
3) In the Premier League, what is the best team? The team that wins Champions League, UEFA Cup, FA Cup or the team with the best record in the end? the team who picks up the most points from 40ish games. (3 points for a win, 1 for a draw, 0 for a lose)
4) Are Transfers basically a team buying a player from another team? Does the actually player get paid the transfer fee or do they sign contacts that is different than the transfer fee? the player does get a bit of the transfer fee but not all and also then get paid what the contract they sign says.
5) If a player's contract is up, does the player have free reign over what team they play for, or is team that has him have a choice of what team he plays for? this is called the Bosman rule basically a player can go to whatever team he wants if they make him an offer.
hope that helped.
