Deschamps has been linked with Roma, Liverpool and Chelsea in recent months.
He told L’Equipe: “Frankly, my future is the last of my concerns. I am fully focused on our objectives this season – the match against Rennes, the Champions League return leg in Manchester.
“Then there will be the cup final and the rest of the Ligue 1 season. That is more than enough to keep me busy.”
Marseille chairman Jean-Claude Dassier said: “We had a meal together on Monday. We talked about the future. I don’t need to answer this question.
“If he is thinking about leaving, he is hiding it well. He left me in no doubt that he is committed to Marseille.”
