Niki Lauda has dismissed rumours Sebastian Vettel will leave Ferrari to join Mercedes in 2018 as "all bulls---"
Vettel is leading the drivers' championship having won two of the opening four flyaway races, helping Ferrari to the top of the constructors' in the process. The team's SFH70 challenger has been the quickest car on race pace so far this year and both Vettel and teammate Kimi Raikkonen are convinced the team can overcome its Achilles' heel of the current decade and successfully out-develop its rivals this year.
As they did at the same time last year when Nico Rosberg claimed his fellow countryman had been "flirting" with Mercedes, rumours have surfaced ahead of the Spanish Grand Prix of Vettel signing a pre-agreement with the reigning world champions.
