Roy Keane has claimed Manchester City star Jack Grealish needs to "grow up".
The £100m summer signing has been under the microscope since his British-record transfer from Aston Villa. In 17 Premier League appearances he has managed just two goals and as many assists for Pep Guardiola's side.
With the likes of Riyad Mahrez, Phil Foden, Raheem Sterling and Gabriel Jesus also competing for a place in Guardiola's frontline, Grealish has endured a frustrating start to life at the Etihad Stadium. Meanwhile, with his off-field antics drawing as much attention as his on-field performances, Grealish has found himself on both the front and back pages this season.
