16-year-old Cameron Humphreys started for Manchester City last Friday as Manuel Pellegrini's side faced Real Madrid. He astonishingly walked out of the MCG cricket ground in Melbourne alongside Yaya Toure, David Silva and Raheem Sterling but perhaps more amazingly was that he was then expected to mark Madrid's fearsome front-line of Karim Benzema, Cristiano Ronaldo and Gareth Bale. The Citizens were comfortably beaten 4-1 but the England U17 International was no more at fault than experienced defenders Bakary Sagna and Aleksandar Kolarov. It's clear that Pellegrini rates Humphrey's highly and it's likely he would like to sign him up when his two year scholarship at Man City finishes at end of the 2015-16 campaign. Unfortunately for the City boss he will have to think quicker as there are a few other Premier League wilder-beasts circulating around the Etihad with a pen and paper waiting for the defender's seventeenth birthday (which is this month) and one of them doesn't have a long journey home. Manchester United are reportedly weighing up the transfer of Humphreys as Louis van Gaal looks to steal the highly-rated youngster from his neighbours. I take a look at look at what all the hype is about and what the Red Devils need to know about their potential new signing.
