Michael Schumacher has turned down an offer from Lotus to come out of retirement and drive for them for their final two races of the season.
The seven-time world champion, who announced his retirement for the second time at the end of last season, was chosen by Lotus following the back injury suffered by Kimi Raikkonen.
"It is true they were asking and I can understand why. Everyone can see Michael is still very fit," the German's manager Sabine Kehm told BBC Sport. "I think it is fair to assume Michael would still be strong but he has happily settled in his new life."
Raikkonen has agreed to return to Ferrari alongside Fernando Alonso for the 2014 campaign.
