Schumacher not about to abandon comeback – spokeswoman
The rumors were triggered at Monza by the German's former team boss Eddie Jordan, who now stalks the paddock as a pundit for British television BBC.
Jordan said on Saturday that he thinks Schumacher, 41, is in danger of vacating the Mercedes seat after spotting multiple team bosses, drivers and managers entering and exiting the German team's motor home at Monza.
"I've a hunch something fundamental has changed. I believe he is disillusioned and thinking of quitting," said the Irishman.
But Schumacher's spokeswoman Sabine Kehm hit back: "Michael has no plans to quit at the end of the year.
"When he entered into the whole comeback scenario, he was fully informed about the situation with the car. That's why he chose it to be a three year contract — you cannot expect to come back and win straight away in that situation.
"Obviously he would have wished that the developments to the car improved its performance more than they did," admitted Kehm.
"But it is a three year project to build a winning team and he is in the middle of the process."
Jordan also said he has "hear rumors" that Mercedes team boss Ross Brawn might not be staying.
But Mercedes-Benz's motor sport director Norbert Haug denied he is at loggerheads with Brawn.
"We are absolutely together working on next year's car," he said.
