"He's only at 70-80kph going into his pit box, so if you can't stop for that then it's obviously a major problem. No ABS in a Formula 1 car."

Sparks are kicking up from the back of Pastor Maldonado's damaged Lotus.

He is down in 18th but is nevertheless giving it his all and he picks off Jenson Button at Turn One to move into 17th.

Jenson Button and Fernando Alonso are some way off a points finish at the moment, running in 17th and 14th respectively with 26 laps gone.

Meanwhile, Lewis Hamilton looks to have eased off his pursuit of Sebastian Vettel, the gap now 1.3s.

Remember when the engine cover blew off Romain Grosjean's Lotus in spectacular fashion during practice? Well, it sounds like he is being warned to avoid that happening again.

He is told over team radio: "Romain, if your don't lift when you hit the bad gear you will blow the engine up. You have to."

Grosjean is currently eighth, behind Daniel Ricciardo.

As Lewis Hamilton keeps up his pursuit of Sebastian Vettel, he may have to keep a close eye on his mirror with Valtteri Bottas flying.

Mike Atkinson: Pastor Maldonaldo's rear wing could do with a bit of gaffer tape...

Dan Leedham: Anyone unsure whether F1 is anything but a team sport, we'll now see how detrimental Hamilton's pit stop issue will be to the result.

Shohidur Rahman: Is it too early to say Nico has this in the bag? I don't think so.

Lewis Hamilton is starting to get a little frustrated, judging by his latest comment over team radio.

"Please, Bono [Peter Bonnington], please try not to speak to me in the corners please," he says.

Discussing Lotus' decision to remove the right-hand vertical element of Pastor Maldonado's rear wing due to damage caused in a tangle with team-mate Romain Grosjean.

"That's a brave call. The centre beam above the exhaust is actually where the structure is supported. The weight coming off the rear tyre is supported by that element.

"He's at sub-optimal aerodynamic configuration."

"Hamilton's putting the hammer down - there'll be a lot of anger in that helmet."

Lewis Hamilton's race engineer: "We're going to have to this [overtake Vettel] on track, mate." Hamilton: "I can assure you that's pretty much impossible to do, so you're going to have to come up with another plan."

Kimi Raikkonen re-emerges on the circuit with the hard compounded tyre bolted on, the only one of those at the front of the pack not to stop for mediums.

Hang on, what's happened here? Pastor Maldonado's rear wing is damaged after contact with Romain Grosjean in the first two laps.

There is a bit hanging off it and it is effectively snapped off with an almighty tug by a mechanic when Maldonado pits, leaving him with two thirds of a rear wing.

Meanwhile up at the front, Kimi Raikkonen leads ahead of Nico Rosberg, the Finn yet to stop.

Lewis Hamilton is back out just behind Pastor Maldonado in seventh and gets the better of the Lotus at Turn 5.

Meanwhile, Sebastian Vettel makes his first stop, in and out in 2.3 seconds, before Nico Rosberg also heads in.

Lewis Hamilton does indeed pit and takes on a new set of medium but oh no! A problem with the left rear and that is a slow stop.

"This is a game of cat-and-mouse on the race track and off it. When you pit now affects the length of your final stint, and the teams are calculating all of that now."

Lewis Hamilton race engineer: "OK Lewis. It's Hammertime. Box, box - do the opposite to Vettel."
