The former Liverpool winger helped his side clinch a 1-1 draw against the Hammers on Saturday.
"I was supposed to sign but they said I've got a problem with the fans," said Diouf. "But I'm a footballer. I can turn the fans around and make them love me. I've done that with the fans at every club I've played in.
"I love the pressure. I know fans are going to boo me and the more they boo the more determined I am to play well.
"It's a big mistake for West Ham not signing me because, if you see from the game, I love Sam Allardyce and he'd love to have me in his team. He knows that when I decide to play I don't think anyone can stop me."
Diouf recently hinted that he will extend his stay with Doncaster.
