As TBH said, I always suggest retraining defensive midfielders! Luis Gustavo is basically a CB who is a bit short to play there, I retrained him to sweeper and he was great! Can be pricey though (I got him for £14m first window)
Thanx all...Ive signed Kara as he fits all the advice here..
Scotty, luis Gustavo is a great shout as well but like you said 14 mill would take a big chunk out my 30 mill. Paid 4.2 for Kara and managed to get Cavani for my Arsenal team.
