text: It’s a shame to see another talented young player being photographed taking ‘hippy crack.’ It might be legal but it’s still a drug. If you want to be a top athlete you don’t want that in your body. In a strange way, maybe this story will actually help keep Jack Grealish’s feet on the ground. He was outstanding against Liverpool but it was one game — he has not made it yet. Jack Grealish (left) has become the third top flight starlet caught on camera inhaling nitrous oxide . Grealish starred for Aston Villa in their FA Cup semi-final win over Liverpool on Sunday at Wembley . At Arsenal, Arsene Wenger changed the attitude completely. He said as professional athletes we had a duty to look after our bodies. Alcohol was described as poison — it slows down your body when it needs to be perfectly tuned. You eat what’s required to refuel, not for pleasure. Of course you still get players who want to enjoy themselves but there has to be a cut-off point. When I see Jack play it’s no surprise that he is full of confidence. He has a big future but he has to make the right choices. That’s how you make sure you are on the back pages, not the front. Emre Can of Liverpool tries to tackle Grealish during their FA Cup tie with Aston Villa at Wembley .
