Meanwhile, former West Ham midfielder Trevor Sinclair and current BBC pundit couldn't help but tease an Everton fan on social media.
A number of West Ham fans took particular delight in Payet scoring the winning goal for the Irons, following James McCarthy's tackle that injured the Frenchman against Everton earlier this season.
