Legit.ng earlier reported that Manchester United are yet to win the Premier League since 2013 despite parading some of the most expensive players in their squad.

The Red Devils recaptured Paul Pogba from Juventus in the summer of 2016 in the club's record deal valued around £89.3 million - the highest the club ever paid on a player to date.

He (Pogba) was part of Jose Mourinho's squad that won the Europa League and the EFL Cup titles but failed to clinch the EPL.
