Barcelona Transfers: 10 Players They Must Sign This Summer

Barca added a new right-back to their ranks as recently as last summer, signing Portugal's Nelson Semedo to a five-year contract after paying Benfica more than €30m.

But the Catalans are nothing if not ruthless. Cesc Fabregas, Alexis Sanchez, Pedro and Arda Turan are just some of the names to have been shown the Nou Camp exit door over recent years, and many of them weren't nearly as dispensable on paper.

Should they look to upgrade again, Real Sociedad's Alvaro Odriozola could be a viable replacement. The 22-year-old has enjoyed a terrific breakthrough campaign in San Sebastian, ending with a place in the Spanish World Cup squad.

It's not the kind of transfer that makes global headlines, granted, but acquiring the long-term services of one of Spain's most promising young players seems like an all-round smart move.
