But Diouf says he'll be back to his best once he recovers from an exhausting seventy game season last year, and laughed off a report linking him to French side Marseille.
He said: "I often phone my friends back home in Dakar and they tell me people are saying I'm going to be transferred to Marseille.
"But I've never spoken about a transfer and I don't think the club will try to sell me so soon after making such a financial commitment to bring me here."
"I'm not on form at the moment. I lacked freshness at the start of the season because of all the energy I used up at the World Cup.
"I played over 70 games last season and I didn't have a holiday, but I don't doubt my ability.
"I've been working hard since arriving at Liverpool and I know the manager has faith in me, so I'm not worried."
