The Senegal international was once again at the top of his game last night as Leeds bloodied the noses of Everton and sent the Premier League high-flyers packing in the Carling Cup at the third-round stage.
Goals from Aidy White and Rodolph Austin ensured that Sylvain Distin's late header was nothing more than a consolation in a 2-1 defeat for Everton, but it was the showing of Diouf that got many talking.
He has rarely been a popular figure during his decade-long stay in England, with Warnock himself once comparing him to a sewer rat.
The pair have formed an unlikely double act at Elland Road, though, and even though Diouf could walk away from Leeds in January, Warnock is sure that they will remain as football's odd couple.
"Dioufy will not go anywhere else, he's promised me certain things and I'm happy with that," Warnock said. "He's obviously not doing it for money, he's one of the lowest-paid players at the club. He's not going to get a stage like this again is he? He's a matador and you need something like that."
