Traore is really raw - this conversations been had a million times on this forum, but he has huge end product but not enough team play - but he’s been improving for the last year, so it’s anticipation that he can keep improving and add that team play to his end product.
Costa and Jota have been the opposite - team play and no end product, so it comes down to what you think is the important thing, people’s views differ. Jota had both last season, Helder was hit and miss due to his injury recovery.
At the moment, the jury is still out on all of them. Can Traore add team play to his obvious attributes and end product? Can Jota make the step up and be as effective in the prem against better players as he was in the champ? And can Helder get back to the kind of form he was showing pre Nuno where he was electric, and his finishing was top drawer, given he’s not been near that level since his injury?
Hopefully all of them will make it, but at the moment there are question marks over them all. The daft thing for me is that people are picking sides and saying x is crap and y is brilliant, when actually none of them are either.
