For free Boulaya i very good CAM. He has great shot power, dribbling and of course 5* skills and 4* WF. The biggest con for me is, that sometimes he can miss a clear chance, because of his low finishing. And to be honest - his long shots are pretty average. But if you play with cheap team like me (futmas lozano on 7 chem, mertens, untradeable sif nainggolan, insigne etc. - but still I'm able to achieve gold 1 with these players) and especially, if you did futmas Atal (who is great), Boulaya is the right one for you.
5* skill moves and 4* weak foot
perfect link to Atal
