Last-start victor Nico Rosberg is seeking to complete a rare hat-trick of successive Formula One wins in Monaco this weekend.
The 29-year-old ended a spell in the shadow of his Mercedes teammate Lewis Hamilton with victory at the Spanish Grand Prix, cutting the Briton's lead from 27 points to 20.
A repeat in Sunday's classic race around his hometown streets will confirm his return to form and add his name to a revered list of Monte Carlo victors.
Not since Brazilian Ayrton Senna won five in a row from 1989-93 has any driver won three back-to-back at Monaco.
Frenchman Alain Prost won three successive races from 1984 to 1986, and again in 1988, a feat that endorsed the era of his rivalry with Senna as one of the greatest.
