Red flag as Roberto Merhi loses his control of his Manor coming out of the tunnel, sliding down to the chicane and hitting the barrier, catching the front of his car on the wall.

Lewis Hamilton is getting faster and faster. He is up into P1 with 1:17.192, putting him ahead of Mercedes team-mate Nico Rosberg.

Jenson Button, who missed a fair chunk of FP1 as work was done on his McLaren, has been out early and is racking up the mileage. He's currently 13th fastest.

Meanwhile, Nico Hulkenberg reports over team radio that Nico Rosberg is slowing down ahead of him, which is not helping his tyres, acknowledged by a slightly frustrated sounding engineer over team radio.

Dafydd Eveleigh I think it's time to throw the rule book in the bin and have one simple rule go as fast as you can as safely as you can.

Thom Hutchinson Give the teams the same prize money each e.g. £100 million to pay staff build car etc. When it's gone that's it for the year. Level field.

Roger Moth Change the designs, allow closer racing and promote overtaking without all these silly aids. Forget the sparks just real fast racing.

There's something new to watch out for later in this session, with Pirelli's red-banded supersoft tyres making its debut.

The compound is said to provide a greater resistance to graining and blistering, which Pirelli believes should offer greater opportunities for overtaking.

"Monaco has often been described as a circuit where overtaking is impossible, but we have seen in the past there how tyre strategy and degradation has often led to positions changing, including on-track overtaking," Pirelli motorsport director Paul Hembery said.

"In particular, the way that drivers use the new super-soft tyre, with its notable performance advantage, will be crucial."

"I was super impressed by Max Verstappen this morning, right from the get go. He was absolutely on it from the start on a circuit he has never visited before. For a rookie to be second in practice in his first time round here is quite a statement."

FP2 is green and Nico Rosberg leads the drivers out on to the circuit for another 90 minutes of practice.

Could we be in for as thrilling a battle as the one at the 1992 Monaco Grand Prix this Sunday?

That race saw arguably one of the greatest battles in Formula 1 history unfold between Nigel Mansell and Ayrton Senna.

Mansell started on pole but an unexpected tyre stop for the British driver during the final stages saw Senna take the lead.

However, with fresh rubber and a faster car, Mansell was soon right on the back of his rival. He battled hard for the final three laps but could not find a way past Senna, who won the race by just two tenths of a second.

Ben Wallcroft: All cars the same! Simple. May the best driver win. OR, each race, a driver has a different car, so every driver gets the chance to drive in the top cars etc. This will prove the best driver and also the best car. If the top drivers are good, they should be able to score points with the less performing cars.

Ben J D Reynolds: Take away all the restrictions and let the teams make the cars as fast as possible. I'd watch it if it had more overtaking and crashing! It's pretty dull in its current format.

Andrew L. Marks: Coulthard was correct in his comments last week; F1 should be about the fastest cars possible being driven by the best drivers possible. It's not rocket science.

A heck of a lot of effort and resources goes into turning the streets of Monaco into a circuit each year.

Around 650 marshals take up their positions around the track on a race weekend, while 33km of safety rails, 20,000 square metres of wire fencing and 3,600 tyres for tyre barriers are brought in and set up.

Work usually gets under way as far back as March too.

Just 10 minutes until second practice gets under way and the drivers are all zipping up their race suits.

Felipe Massa: "Maybe we need to make the tyres wider to give more mechanical grip. We need to be a little bit quicker, through the years the cars are getting slower and slower, maybe we need to make the cars a bit quicker and maybe make them look nicer, they looked amazing with the aerodynamic pieces in 06 and 07, after 2004 the car just got slower year on year."

Jenson Button: "Refuelling can be unsafe but I love the racing we had with refuelling, you can make the racing more fun it will bring something different to the sport."

Daniel Ricciardo: "No-one's going to say they don't want to go faster, I don't think we're fast enough, and we're well within the limits, go quicker that would be awesome, bit more noise might put us back up to more heroic status' as drivers."
