Feb.21 (GMM) Ralf Schumacher has said the advice of his elder brother Michael to avoid DTM is an "added incentive" to do well in the German touring car series.



Before 32-year-old Ralf committed to switching to the category with Mercedes-Benz in 2008, former seven time world champion Michael Schumacher - who is seven years older - warned him to stay away.



"I believe that neither of us have the talent to drive those cars quickly -- I have even tried them and it is a completely different world," Michael said in January.



Now that he has signed a minimally one year contract for 2008, Ralf was asked by the German newspaper Bild if he contemplated heeding his elder brother's advice.



"It is more of an incentive for me," he said, amid speculation that the German brothers no longer have a close relationship.



"To find out if it comes easily to me or not, I can only try, so we will see," Ralf added.



Schumacher also indicated that he may attend some grands prix in the future.



"If I come to the formula one paddock, I will certainly eat my supper in the Mercedes motor home," he vowed.
