Vettel blames back-markers
Red Bull drivers Sebastian Vettel and Mark Webber had mixed reactions after finishing fourth and fifth in the Canadian Grand Prix.
The result means Webber drops from first to third in the drivers' championship, behind Lewis Hamilton and Jenson Button, with Vettel now fifth.
The team has also lost the leadership of the constructors' championship, falling 23 points behind McLaren.
Webber said: "In the end we did the best we could do."
The Australian continued: "There are mixed emotions after the penalty [five places for a change of gearbox, demoting him from second on the starting grid] this morning and starting seventh, but then I had a good first few laps and managed to get into a good few people. But that took its toll on the tyres, so it was not too bad.
Vettel was left wondering what went wrong
"I knew everyone was pretty close together and I was monitoring the gap to Lewis. I was just trying to get to the end and hold my pace constant but the tyres did not want that pace, and it was almost impossible to keep the tyres happy.
"In the end I'm not that surprised. I wanted to get some champagne today but in the end it didn't happen."
But Vettel, who started second and ultimately had to back off with a mechanical problem, was unimpressed by the driving of the backmarkers.
"We had a gearbox issue and in the end had to save the car and bring it home. I think we did the right thing with tyres, everything worked and happened according to our plan, the others survived very little on the soft tyres at the beginning so they had to stop early.
"They should have come out in traffic and their race is over, but it didn't happen. Halfway I had a lapped car which didn't want to move which lost me six seconds each time, and in the end I wasn't able to fight for the podium any more."
Team principal Christian Horner said: "We shouldn't be too disappointed, we always knew this race was going to favour the McLarens. We were actually more competitive here than we expected to be which I think is an encouraging sign.
"Valencia plays to McLaren's strength again, lots of straights, and then we come back to tracks like Silverstone, Hockenheim and Hungary that play more to our advantage.
"There's a long way to go in the championship and it's important on days like this that we limit the damage."
