 Diouf began the 2015–16 season well scoring in draws against Tottenham Hotspur and Norwich City in August and the winning goal against Bournemouth, in September to secure Stoke's first win of the campaign.However following the death of his mother in September 2015, Diouf lost his form and consequently lost his place as centre forward with Mark Hughes instead using him in a winger role.Diouf even had to fill in a right-back against Bournemouth in February 2016, following injuries to Phil Bardsley and Glen Johnson.
