Ex-Australia opener Matthew Hayden said England all-rounder Ben Stokes has a chance to become CSK's X-factor this season. "Stokes has never realised his potential in IPL...Now, under a CSK regime where it's all about cricket I think he's got a big chance," stated Hayden. So far, Stokes has scored 920 runs and picked 28 wickets in his five IPL seasons.
