Roberto Martinez called Nuno Mendes the ‘best left-back he’s ever seen’ and backed the Portugal star for the Ballon d’Or award after an incredible season.

Mendes played a crucial role in Paris Saint-Germain’s historic treble, which included their first-ever Champions League title.

The 22-year-old also scored a goal in normal time along with a penalty in the shootout as Portugal beat Spain to win their second Nations League.

National team manager Martinez hailed the defender’s performances this season, calling him a level above the rest.

“I used to think that the perfect player didn’t exist, but Nuno is very close to that,” Martinez told TNT Sports.

“For me, Nuno Mendes is the best left-back I’ve ever seen. He can play out wide or inside. He’s very fast and has great passing ability.

“Mendes and Vitinha are way above the rest, both at club level and in terms of their profile.”
