Michael Schumacher should stay in Formula One for as long as he wants to.
That is the claim of Franz Tost, the Austrian team boss of Red Bull's second F1 team Toro Rosso.
According to Der Spiegel, Tost knows the 42-year-old German well, and so he was asked about widespread speculation that Schumacher should return to retirement rather than race on in 2012 and beyond.
"First of all," replied Tost, "Michael Schumacher, the seven time world champion with nothing to prove, should not care whether his teammate Nico Rosberg is faster than him or not.
"What is crucial for him is whether it is still fun or whether the passion is still there. These are questions only he can answer."
But figures like Eddie Jordan - Schumacher's first ever F1 team boss 20 years ago - have said they would now dismiss the famous German due to a lack of performance.
Tost responded: "Michael brings so many other advantages that outweigh that. Do you think Mercedes would still be so much in the spotlight if Michael Schumacher left?

"This is a crucial factor. He continues to attract huge amounts of attention and so I see his comeback as anything but negative."
Eddie Jordan however told Dutch website f1today.nl that Schumacher has "had his day".
"This sport has had many champions and Michael Schumacher has had his day," said the Irishman.
"He has had huge success and is a very good driver, but someone should talk to him and try to convince him to let his place be taken by another talented driver."
