Sir Jackie Stewart has tipped fellow multiple world champion Michael Schumacher to keep racing beyond 2012.
“He has had a lot of criticism including from me,” Stewart told Kolner Express.
Triple world champion Stewart, 72, said the famous German has taken a lot of time to get back up to speed since returning in 2010, but the final piece of the puzzle is a strong Mercedes in 2012.
“He has had a hard time. So why should he stop now that he knows he can still keep up with the boys? I think he wants to collect the fruits of the work that he has been doing with Mercedes.”
