Schumacher isn't convincedRalf Schumacher does not think Christian Horner's widely-rumoured Formula 1 comeback will be with Aston Martin. I can't imagine Christian Horner coming back as team principal, certainly not under anyone with the character of Lawrence Stroll, he told Sky Deutschland. Instead, Schumacher recalls that Jonathan Wheatley is widely tipped to take over as team boss at the Silverstone based team. What would Christian Horner do at Aston Martin? As for Aston Martin, Schumacher said the presence of Adrian Newey also makes a reunion difficult to imagine.
