Lancaster is expected to undergo an interview with the Rugby Football Union before the close of the Six Nations campaign, but has insisted that the national squad are fully focused on taking on France.
"There's a lot going on in terms of preparation for those two games but I'm comfortable preparations are as they should be," said Lancaster.
"I can't control the timelines. All I can do is do this job to the best of my ability and I can guarantee that's what I'll do."
England's final match of the tournament is against Ireland at Twickenham on March 17.
