SPA, Belgium -- As Mercedes tries to get to grips with the latest dispute between its two bickering drivers in their tussle for the Formula One title, Red Bull is quietly enjoying an encouraging return to form.
It has been a difficult season for Red Bull, which had won the past four drivers' and constructors' championships thanks to the previous dominance of its car and the consistency of four-time defending champion Sebastian Vettel.
The roles have been reversed, with Mercedes rolling over everyone for most of the campaign and Vettel struggling.
Red Bull has won the past two races, however, with Daniel Ricciardo following his success at the Hungarian Grand Prix with another win at Sunday's Belgian GP.
In those races, Mercedes finished third and second, conceding some ground in the constructors' championship.
