The midfielder is under contract with the Catalans since 2011. Due to an injury he has been out for the long term and would like some first team football. Currently he has a contract until 2015. Apart from Ajax interest, Arsenal seem to like the services of the Spaniard.
Both FC Barcelona and the player earlier in the year did not see this transition to Amsterdam happen. Now, however, the 21 year old still seems to want to make the switch happen.
