Input: Jon Walters is the kind of footballer who holds up an imaginary substitutes’ board when a referee goes down injured, who picks up a matchday programme hurled in his direction and has a flick through. During Stoke’s victory at Aston Villa last month, his reaction to referee Roger East’s attack of cramp was more comic than concerned. It was similar when an irate Newcastle fan chucked the makeshift missile as celebrations followed Peter Crouch’s equaliser. ‘A referee with cramp! Can you believe it?’ chuckles Walters. ‘He needed to come off, didn’t he? The programme was a good read. 10 out of 10. You’ve got to enjoy yourself.
