World's most expensive XI

Right-back: Kyle Walker

The former Tottenham defender continues to impress with his speedy runs from the back.

Transfer: Tottenham Hotspur to Manchester City.

Transfer fee: € 52.7 million

Another world-record transfer, another Manchester City player. To be fair, Walker's performances were on an exponential high when City broke the bank to sign him. His spectacular performances at the back have been nothing but a sweet reward for the Premier League champions.

28-year-old Walker had played an instrumental part in Tottenham's rise to recognition in the season when they finished third to champions Leicester. No wonder, Pep snapped him up at the first chance. His pace has proved extremely beneficial to the Citizens' counter-attacking style.
