Vettel tops second practice times

However, struggles set in after lunch as the Brit complained over the radion of being unable to get heat into the tyres while F1 World Drivers' Championship leader Sebastian Vettel was the first man into the 1min12s, leading the field by almost half a second.

Daniel Ricciardo of Australia and Red Bull Racing prepares to drive during practice for the Monaco Formula One Grand Prix at Circuit de Monaco.

World championship leader Sebastian Vettel went quickest for Ferrari with a lap of 1m 12.720s - more than a second faster than Hamilton. Symonds, himself watching the action at the Rascasse, believes the ability to get on the power early out of Monaco's tight corners is also marking cars out.

"In myself yeah absolutely [I have confidence]", he said.

"Around here, it's important to have a good feel for the auto", Vettel said.

It was the first time Button has driven a 2017 spec auto and he admitted the new machines will take some getting used to. We are still obviously not sure.

"We changed our settings between the first and second sessions, except that we made the wrong decisions", Bottas said.

The afternoon proved to be a different story.

Vettel, who won his four titles with Red Bull from 2010-13, sounded optimistic that Ferrari can carry the pace into Saturday's third practice and qualifying. Ricciardo told journalists after his run.

"We put some good laps together and know where we need to improve so I'm very happy with our position after the first day".

Raikkonen was happy that changes made to his SF70H during the day seemed to work to make the auto faster, and only small things will need to be changed between today and Saturday.

"I think they will find more tomorrow", said the German Vettel. Then you feel really uncomfortable because you think, maybe I am too close to the barriers. "Wider auto and wider tires - it makes the track more narrow I guess".

"After a very positive morning session with both cars and drivers, the afternoon proved more hard and we clearly took a step in the wrong direction with the vehicle set-up over the break", Mercedes' technical director James Allison said.

"We didn't have the greatest day", said Hamilton.

Max Verstappen was just three tenths off the pace in the first free practice session in Monaco on Thursday morning. "They probably had a problem today, but I am sure they will be back to full force on Saturday".
