Arsenal hero Martin Keown says Aston Villa midfielder Jack Grealish has allowed fame to go to his head.

Keown wrote in the Daily Mail: "Jack Grealish has to learn quickly because at the minute nothing seems to sink in. In life you learn from your mistakes and if you keep making them, you can only blame yourself.

"I was an Aston Villa player who was relegated so I know what it's like to go home on a Saturday night after a bad defeat. I certainly don't remember going out partying.

"All plans were off if you lost.

"Sometimes I don't think players understand how much these kinds of photos hurt the fans. "There will be thousands of Villa fans who are Jack's age who would give up everything to be in his position."
