World's most expensive XI

Left-back: Benjamin Mendy

Pep Guardiola bought the World Cup winner from Monaco last season.

Transfer: Monaco to Manchester City.

Transfer fee: € 57.50 million

The Senegalese-born French national Mendy has one colorful life (you only need to see his social media). The recently-crowned World champion is considered to be one of the best full-backs in the world.

His stunning display at the back for Monaco convinced Pep Guardiola to bring him to the Etihad. After a slight nudging, Monaco finally agreed to sell their charismatic defender to Manchester City for a world-record € 57.50 million.

While Mendy is yet to show that potential which made Guardiola shell out so much money, a fit Mendy can prove to be a solid wall and a potent attacker at the same time for the Premier League champions.
