If a team aspires to be at the top level, reaching the latter stages of the Champions League and competing for the title, which of these would you actually say are good enough?
Ok just label them like;
Sell - not good enough
Back-Up - Back up player in case of many injuries.
Rotation - In squad to rotate for first teamers to keep fitness levels up or injuries.
First team - Someone who is in the first team but isn't a guaranteed starter.
Starter - Someone who ideally would start every game.
Also if they're young then say if they'd be a potential starter or first teamer.
