On-loan Sunderland striker Djibril Cisse has reiterated his desire to stay at the Stadium of Light, but fears uncertainty surrounding his future could be damaging his form.
The Frenchman is currently on a season-long loan in the North East from Ligue 1 side Marseille and it is unclear where he will be plying his trade next term.
Cisse has made no secret of the fact that he is keen to remain with the Black Cats, however, manager Ricky Sbragia has stated that no talks will take place until the club's Premier League status is assured.
But while Cisse remains desperate to agree a permanent career with Sunderland, the former Liverpool player - who has scored only once in his last nine games - worries a lack of long-term assurances is impacting upon on-field matters.
"Maybe it has been difficult for me," he said in the Daily Mail.
"It is not nice to worry about your future and to think about the uncertainty, and perhaps I am distracted but I have to deal with it.
"I want my future to be here but I'm still waiting to sign. I am waiting, I am patient.
"People were surprised when I left one of the best clubs in France and a team in the UEFA Champions League to join Sunderland, who were involved in a relegation fight last season. But I was not satisfied in Marseille. I want to score goals and you can't do that from the bench.
"That's me. I want to play and score goals and when I don't I'm not happy. I feel I'm not doing my job properly."
