Sorry, but who out of them would you not want in some sort of capacity at our club now? Bearing in mind we have Kone as a back up striker.
The problem with this though is you're seeking an answer that doesn't adequately portray the context of the original post, or our future desires.
Would I prefer Tello, Allefay, Deloufeu, Bojan or Traore over Koné? Well yes obviously, but it's not an option of simply comparing to one player.
A more suitable and realistic question is whether in the Summer would people be happy with signing the likes of of Tello, Allefay or Bojan?
Personally, I'd sincerely doubt whether either of those players would be good enough signings - even merely as squad player in some instances!
The point, which I tend to agree with, is that Barcelona outcasts are often unjustly labelled as fantastic players simply because they're from Barca.
