Ranking the 10 best left-backs in the world

#5 Marcos Alonso (Chelsea)

Alonso has become a top left back since his move to Chelsea

Fans of Bolton and Sunderland may be surprised to see Alonso appear on this list, because he appeared for both of those sides earlier on in his career, and although he wasn’t too bad, he didn’t really set the world alight. It has been a different story since he returned to England though, under Antonio Conte at Stamford Bridge. Conte must take a lot of credit for this, because he identified Alonso as the man to solve his problems at left wing-back, and he was absolutely spot on.

He has the engine to get up and down the pitch, and he plays a role in both penalty areas. He is a good defender, and proved that by helping Chelsea win the Premier League in 2017. He also has one of the best left foots in the world, and showed this off against Tottenham at Wembley last season, netting a stunning free kick. He has started well again this season, but he will be tested more this year, because he is now playing in a back four under Maurizio Sarri, and has greater defensive responsibility.
