Engineer: "We must save fuel, we must target zero. "

Fernando Alonso: "I don't want to. I don't want to. Already driving with... looking like amateur, I will race and then concentrate on the fuel."

Raikkonen has just come unstuck on his new tyres. He looks smooth through the hairpin but suddenly the front and rear ends swap places and he's left sitting in a cloud of tyre smoke facing the wrong way.

"Exactly the same happened last year!" the indignant Finn proclaims on the radio.

The Ferrari comes in and puts on the soft tyre. He rejoins fourth, losing a place to Bottas for the time being.

"Lewis Hamilton is absolutely flying. He just did a lap three-quarters of a second faster than team-mate Nico Rosberg. He is absolutely devouring this circuit."

Mercedes on Twitter:, external Gentlemanly as always - Jenson gives Lewis plenty of room at the hairpin. Lewis is on a mission today!

"Mercedes are going well here on those tyres - 22 laps in. If they get to lap 30, that's a comfortable one-stop."

Hamilton is getting the hammer down here. With pit stops approaching, he extends his lead to 4.5secs over Rosberg.

After his earlier scares, Vettel does get past Alonso as they hare down the start-finish straight.

He has since made short work of the Toro Rossos of Verstappen and Sainz.

P13 now for the Scuderia driver.

"That was a bit optimistic from Sebastian - he got himself on the outside. Alonso is a racer, even though he is in a car which is the slowest in a straight line."

Vettel is getting ragged as he tried to make his way through the field, running on to a slither of grass on the exit of turn six before failing with an attempted pass on Alonso into the final chicane, the Ferrari bouncing over the big kerbs.

"Check the front-right corner. I touched with Alonso," the four-time champion tells his team on the radio.

Phill Alan Russell: We need a Maldonaldo spectacle to spice this race up a bit!

Pogba: I don't think Nico has any answers to Hamilton at this moment. I will bet he has his mind on a safety car.

Bishop Yinkus: Star driver of the day so far is Massa, what a race he is having this evening.

1986 Canadian GP winner Nigel Mansell: "Great to see Lewis and Nico playing chess with one another at the moment, they just driving well within the car, just looking after it."

Massa zones in on his next victim...

"Felipe Massa has never actually out-qualified his team-mate at this circuit. It's always interesting to me how some circuits are more suited to some drivers than others."

Red Bull team boss Christian Horner talking to BBC Sport: "It was a bit depressing really [to see Felipe Massa pass Daniel Ricciardo]. It was an easy pass for Massa but we are not really racing them. It looks like we are racing Force India. The big question is whether it is one stop or two stop. That is what we are weighing up at the moment."

The Felipe Massa Show continues with a pass on Sergio Perez for ninth.

The two drivers had a massive coming-together late in the race last year but no such drama today.

"So far, it doesn't look like Rosberg has any answer to Hamilton."

The gap is out to 3.3secs on lap 15.

Nico Hulkenberg: "My front left tyre is looking pretty ugly. It's getting worse and worse."

Nick Phillips: Ericsson, since going to Sauber, has really shown that he can race. Great stuff between him and Massa.

Callum Rowe: That Massa and Ericsson was incredible. Precision racing at its best.

Steven J.M. Heap: Proper racing from Massa and Ericsson. All nicely done. Thrilling stuff!
