Another thing to think of also is the rivalry.
The top 4 teams very rarely, if ever, sell players to each other because - what's the point in selling a player to a rival and help them?
Everyone (mainly the press and fans themselves) are always preocupied with "beating the top 4" when in fact you've got to look at where you are and who are threatening your position. If you split it up into different leagues our rivals in our mini league would be - Villa, Spurs, Citeh.
So selling Lescott doenst also create problems in our own transfer targets and team, but we're also giving one of our main rivals and massive boost to finish above us in the league.
Yes, Citeh gave us Jo, but Jo will never play a game a Citeh and would be at another club. They're also wanting Lescott so more fool them for sending him our way.
Its like Villa selling Ashley Young to Citeh, or Modric to us - key players going to help your closest rivals isnt a good step to make. So £20million and Lescott goes the other way ends up with Citeh finishing above us or at a push beating us in a semi final of a cup is going to be a done transfer isnt it?
