Aston Villa boss Martin O'Neill insists he didn't want to lose any of his young players.
O'Neill this week let Luke Moore join West Brom with a view to a £3.5m deal.
That follows the sale of three more youth-team products Steven Davis, Liam Ridgewell and Gary Cahill.
O'Neill said: "There's not been a player I wanted to force out.
"But we have raised £15m from selling these players and most have sell-on clauses.
"It gets to the stage where I have to do the best for the football club."
