Tim Sherwood issues Jack Grealish warning

Aston Villa boss Tim Sherwood has warned Jack Grealish after the midfielder was pictured inhaling nitrous oxide.

The 19-year-old has been photographed taking the legal high from a balloon, with the picture published in the British press on Thursday morning understood to have been taken a year ago.

Grealish follows Liverpool winger Raheem Sterling and West Brom striker Saido Berahino in being pictured taking the legal high.
