Nico Rosberg collected his first victory of the season after winning the Spanish Grand Prix on Sunday - but after reducing the gap to Lewis Hamilton can he challenge his Mercedes team-mate for the World Championship?
Rosberg is now 20 points behind the reigning World Champion, with Hamilton finishing second in Barcelona and being unable to match the pace of Rosberg throughout the race weekend.
As Formula 1 heads to the Principality for the Monaco Grand Prix on May 21, Rosberg will be confident of closing the gap even more to Hamilton, as he has won in Monaco and taken pole position in each of the last two years.
But just why is Rosberg so quick around the streets of Monaco? He loves the circuit as he lives in Monaco, and as he considers it to be his home grand prix he always pushes himself to the maximum on the tight and twisty streets the glamorous track has to offer.
In terms of the World Championship, however, will Rosberg be able to deny Hamilton back-to-back titles?
On more than one occasion last season, Rosberg struggled under the pressure Hamilton put on him, as he made high-profile errors in Monza for the Italian Grand Prix when leading and at the inaugural Russian Grand Prix, while at several other races he was considerably slowly than Hamilton.
Hamilton as a two-time World Champion has the experience of keeping a cool head during pressure situations, and given the Briton has won three of the five races so far this season and finished second in the other two, it is going to be difficult fo Rosberg to break Hamilton's mentality and be quicker than him throughout the season.
With the Spanish victory to his name, Rosberg has kick-started his season, and with Monaco coming up will be looking to continue the momentum he currently has after outperforming Hamilton throughout the Spanish Grand Prix.
In order to challenge Hamilton for the World Championship Rosberg must perform like he did in Spain at every grand prix, but given the way his championship challenge faded last season and only having one win so far in 2015, Hamilton still has the edge over his team-mate and will not be worried about the German for the moment.
