Team boss Ross Brawn on Thursday would not be drawn on speculation Michael Schumacher and Mercedes have now agreed to stay together at least another year.
German commentator Christian Danner, a former grand prix driver, earlier brought the seven time world champion’s uncertain future back to the headlines when he revealed he thinks Schumacher, 43, has decided to stay in F1 in 2013.
"I ask for your understanding that we are not going to constantly give statements about our decision-making process," team principal Brawn told DPA news agency.
"As soon as a decision is made, we will inform you about it," he added.
