Over the past 5 years their policy has been hugely successful. they've sold players like Reyes, Baptista and Ramos for huge fees - other clubs might have tried to hang onto them to help build a serious championship challenging side, and after every sale, there were worries that the squad would be degraded. But in fact the opposite has occurred - its almost as though the sale of their star players has strengthened the side.
Not only have they been shrewd with sales, but also with signings bringing in players like Poulson and Kanouté who have gone from strength to strength.
Like Villarreal they have also been successful in bringing over talents from South America, like their full backs Daniel and Adriano and they have also been chruning out some great youth prospects, this most recent of these to be a great success has been Jesus Navas.
Have any other teams in Europe come anywhere close to this success?
The only team I feel comes close is Villarreal, certainly I can't think of any teams in Serie A or the EPL
