And the 29-year-old is optimistic ahead of the clash against Mauricio Pellegrino’s charges.
“If you look at the first seven or eight fixtures we have had then it is quite incredible,” Diouf told club website.
“I don’t think anybody expected us to get much from our opening three or four games, but we did very well in those matches.
“We showed good character and performed well, but things have slip a little bit since, which has been disappointing.
“We beat Arsenal, we drew with Manchester United and then we lost to Newcastle United, when everybody thought we would win.
“People may look at this fixture with Southampton and think Stoke are at home, they will win that one, but football doesn’t work like that.
“We are at home this weekend though, we have to dictate what happens and hopefully we can do what we have done against Arsenal, Manchester United and even Chelsea, who I thought we played pretty well against."
