Barcelona Transfers: 10 Players They Must Sign This Summer

Chelsea's failure to qualify for the Champions League will have definitely caught the attention of Europe's big boys, particularly as regards the uncertain futures of Belgian duo Thibaut Courtois and Eden Hazard.

Another name that could be on the move, however, is left-wing-back Marcos Alonso, who has emerged as one of the Blues' most reliable performers since his move from Fiorentina two years ago.

As well as the lure of Europe's premier competition, the 27-year-old may also see a move back to his homeland as a good way to improve his international prospects, having been harshly cut from Spain's World Cup squad in favour of Nacho Monreal.

Like it or not, turning out every week for Barcelona gives you a much better chance of representing La Roja than playing at Stamford Bridge, especially when your side are languishing down in fifth place.
