The deal will do good for both clubs.. Caceres is not needed in Barca and not suit Barca style of play.. We have too many DM although Poulsen start to perform better than last season, and Poulsen is known to have a good passing range ability in La Liga before, it will suit Barca style of play.. Do this swap deal then..
If Tiago go to Wolfsburg is true too, it will be great. Also sell Moli to Napoli
