West Ham playmaker Manuel Lanzini could face a ban for diving during Saturday's Premier League win at Stoke. The Argentine fell to the ground as he was challenged by defender Erik Pieters and the Hammers were awarded a penalty, which put them 1-0 up in a 3-0 victory. The incident has now been referred to a Football Association Independent Regulatory Commission. Stoke boss Mark Hughes claimed Lanzini "clearly dived", while West Ham boss David Moyes blamed Lanzini's "fatigue". The FA panel includes one former match official, one ex-manager and one ex-player, and all three have to agree for a ban to be enforced. "Whether or not he is or not, it doesn't help us," said Hughes.
