It has been put there deliberately to create some more tension in the situation , said Howett about the Express report , while talking to British newspaper The Daily Telegraph . I don ' t know the source , but I can only say in our case that there is a clear wish to enter next year ' s championship . Toyota announced it ' s withdrawal in November 2009 . Mercedes is not going to suddenly announce they are going to quit one day . If they are going to quit there will be rumors around . I don ' t think there is any reason to speculate about them quitting in the next year or two . They will be around till 2020
