Nico Rosberg sure Mercedes was the best car in Monaco

Rosberg started from second position behind Webber, who made a good start from pole to keep his lead.

The Australian managed to keep his Mercedes rival at bay despite intense pressure, Rosberg crossing the finish line 0.6 seconds behind Webber's Red Bull.

Rosberg was very happy with the result despite not managing to pass Webber for the lead.

"My engineer and my team gave me a great start, I got away really well," said Rosberg. "We were miles ahead of everyone else but I was not able to get him. After that, Mark drove a great race, very controlled.

"In general it has been a good weekend for me and team. I think I had the best car, that is my feeling. That is really cool and let's hope there is a lot more to come in the next few races."

Rosberg, who scored his maiden Formula 1 win earlier this year in China, said being on the podium in Monte Carlo was very special for him.

"It is very special to be up here, and it is great the way to the podium was my way to school, so I am very happy," he said.

Despite the nature of the circuit, Rosberg admitted he was hopeful he would be able to pass Webber, but said his tyres were gone by the end of the race.

"I was hoping I would get the chance but my tyres were really struggling too. I had Fernando [Alonso] behind me. At times it was very difficult. The tyres lost temperature, and they then picked up towards the end."
