Samper, Rakitic, Xavi midfield would really be intriguing. Such an intriguing mixture of ascending youth(Samper), prime shape(Rakitic), and veteran experience in the twilight of his career(Xavi). Would be very interesting to witness.
Plus Roketic will be able to play the attacking mid instead of the Don but where would that leave the right wing without him covering for the bombing winger unless Douglas stats as a defensive fullback
