Except barca doesn't expect players to come to them, and neither do Real Madrid
it's the players that know they are wasting their careers in liverpool when they have outgrown that a team that's won nothing in how long now?
In cases with spurs/pool/arsenal they aren't winning anything so players get restless and easily tempted by teams with better chances.. that or cash in their careers for a big fat contract
those teams are tier 2 clubs, like sevilla and valencia.
they do the same to tier 3 clubs and so on so on... don't act like we're the only club that tempts players.
