The footballer eats a bowl of coco pops on match day mornings, according to Ladbrokes, and practices visualization techniques to get his mental state in check.

In his book "My Decade in the Premier League," he wrote: "The club like us not to go overboard on the eating and drinking in the close-season break, so if I go abroad I like to get into the hotel gym three times a week to work on the treadmill and do some weight work. That way I can be sharp when we get back to training and the running will feel easier when the pre-season games start."
