Andre Gomes - 21%
Our users have been pretty clear: the Portuguese midfielder is the biggest transfer flop. Gomes joined Barca from Valencia for €37m and spent two miserable years at Camp Nou.
Philippe Coutinho - 19%
The Brazilian tried hard but his enormous transfer tag has made things difficult for him. Signed for €145million just 18 months ago, Coutinho is currently on loan at Bayern.
Arda Turan - 12%
The former Atletico Madrid man has never managed to make any impact on the Catalans. Arda has returned to native Turkey as he is at Basaksehir.
Ousmane Dembele - 10%
The Frenchman has never managed to become close to Neymar. His two-year tenure at Barca is highlighted by injuries and tensions with the club. The Catalans are now trying to swap him for the same player he was signed to replace.
