As Alex Hunter in story mode, players can choose which clubs they join. A die-hard Everton fan will never be required to play for Liverpool. But performance is key. If you want to play for one of the bigger Premiership sides, you'll need to be good. Sub-standard performances will be punished by a spell on the bench or even in the reserves. All these eventualities trigger story sequences.
Hunter can get himself back in managerial graces by using practise mode to demonstrate the necessary skills. Hunter is a forward who can play left, right or center, so there's no option to make him a defender (or Midfielder). He can be played either as an individual or as the whole team.
