Sebastian Vettel's end-of-season slump may be due to "family problems"

Italian broadcaster Sky claims, that Sebastian Vettel’s end-of-season slump may be due to “family reasons”, as the German driver’s championship rival Lewis Hamilton stands on the cusp of wrapping up the title in Mexico. Referring to the supposed 'family problems', a source at Sky Italia said: "We can't say anything more because it's his private business." According to Brazil's Globo, Mercedes got wind of the protest threat and filled the holes in with silicon. It could explain why Ferrari was suddenly back on Mercedes' pace in Austin. "We have a battle on our hands and we will have to keep pushing to win both titles," said Mercedes team boss Toto Wolff ahead of the Mexican Grand Prix. Hamilton needs only a seventh place in Mexico to secure his fifth drivers' world championship. "It has been one of the weaker tracks for us in previous years and we expect a hard fight," Wolff insisted.
