Man... I mean he wouldn't even be a starter at clubs like Valencia and Sevilla, we don't even need to talk about best PL clubs and Bayern.
As I already wrote he has been receiving privileges at Barca because he's a catalan from La Masia.
Semedo in Abidal role ? Why not. But Semedo is now also 5 times better at attacking than Roberto. Semedo is better than Sergi at every task you could ask from a right back. Semedo's only defect compared to Roberto is that he's not catalan and not from La Masia. Plus Valverde might have shit in his eyes.
I said in an Abidal role because I dont trust Pique nor Bus or Raki to defend the space he leaves behind his back, plus, we already look so vulnerable defending in a counter attack situation.
