All Rosell should be doing if the Cesc deal goes through is buy cover for right back , centre back , and a wide midfield player. Villa and Cesc will cost Barca around 75 million. So Barca should try and trim the costs by selling guys like Henrique , Cacares , Hleb , Chygrinski , Henry , Marquez , Yaya Toure. That group of players would recoup about 40-50 million. which would leave Barca's net spend at 25 million , which isn't alot. For cover i think Barca should use Botia , Bartra , and perhaps Muniesa. Also taking into account if Zlatan leaves , which will take about 40 million , Barca will have more than enough to buy one more world class player. I could see it being between Torres , Mascherano , Sillva , or Mata. Even though Barca's La Masia is the best in the world , i think Barca would be wise to invest in some of the top young players in the world. Maybe try for Neymar , ease him into the first team , perhaps a loan deal, or his Santos team mate Paulo Henrique Ganso who is been tipped for a huge future.
