David Coulthard insisted he was not wanting to point any fingers of blame after a bungled second pit-stop in the inaugural Singapore Grand Prix at the weekend cost him a likely fourth place.

Though he still went on to take the chequered flag seventh - fending off the aggressive late-race attentions of Williams' Kazuki Nakajima to secure only the second points-scoring finish of his valedictory campaign in Formula 1, more than three months on from his Canadian Grand Prix podium - Coulthard was aware that it could have been so much more.

After running in the 'Trulli Train' in company with Red Bull Racing team-mate Mark Webber early on, the 37-year-old Scot similarly benefited from the Milton Keynes-based concern's excellent reading of the safety car situation following Nelsinho Piquet's crash on lap 13.

By astutely bringing both cars in to re-fuel before the safety car was released on-track, Webber and Coulthard lay in net third and fourth positions approaching the race's halfway point, and after the Australian was forced out of contention with gearbox woes on lap 30, the sister RB4 moved into a podium position.

Coulthard went on to draw upon all of his experience and guile to fend off the McLaren-Mercedes of F1 World Championship leader Lewis Hamilton - who described the 13-time grand prix-winner as having been 'a good second slower than everyone in front of us', even if he acknowledged that his fellow Brit had driven 'a fantastic race' - until the Stevenage ace finally found a way past when eventual race-winner Fernando Alonso rejoined from his second pit-stop right ahead of the RBR.

Still looking good to take fourth place, the man believed to have been signed up to help front BBC's coverage of the sport next year [see separate story - click here] lost precious seconds when he was prematurely released during his own second pit visit, and a subsequent braking issue saw him slip back to seventh spot at the chequered flag.

"That was my second points finish this year," Coulthard reflected afterwards, "so I've got to be happy with the result. As far as the second pit-stop went, the guys have been great this year and the work that they did on Saturday morning to get my car out so I could do a run was quite remarkable, so I'm not going to point any fingers at them. It's just one of those things.

"There was a misunderstanding between some of the guys and I go when the lollipop comes up, but these things happen. Thankfully we got some points. It was incredibly bumpy out there - you can't see the braking down into turn seven - and it was as hot as hell."

"I lost seventh and then fifth gear," explained a naturally disappointed Webber, "which cost us a fantastic result, as I was stopping for my second pit-stop later than Fernando. It would have been nice to share the podium with him, with him winning and me second.

"We got a bit lucky with the safety car, but in the end it didn't work out. We had some good pace in the second stint and it was looking good. Overall, the event here has been very impressive - I think we should do more night racing."

Having ultimately left Singapore with just two points - rather than the eleven it had at one stage looked good to score - Red Bull ceded further ground to chief rivals Renault, Toyota and Scuderia Toro Rosso in the constructors' world championship on a day when it could have taken a significant step forward.

What's more, Nico Rosberg's runner-up position and Nakajima pinching the final marker in eighth allowed Williams to close to within just two points behind as well - a fact far from lost on the energy drinks-backed outfit's team principal Christian Horner.

"After putting ourselves in a great position with a good call that enabled us to get both cars fuelled, serviced and back out on-track before the pit-lane closed, it was really frustrating for Mark to lose a definite podium with our first mechanical failure during a race this year," the Englishman affirmed.

"David thereafter was doing a great job. He held Lewis off for a large part of the race, but then dropped three seconds on his in-lap when Fernando popped out from the pit-lane just ahead of him. He then lost more time at his final pit-stop.

"That cost David what would have almost certainly been fourth position - so seventh, albeit his first points score since Canada, leaves us feeling that we should have come away with more.

"Congratulations to Renault on their win with Fernando. Well done to our mechanics too, who have done a fantastic job this weekend. The technician who was knocked over during David's final pit-stop has damaged his ankle ligaments and burned his thumb, but fortunately other than that he's okay."

"A very frustrating day," concurred Renault principal track support engineer Fabrice Lom. "We should have been second with Mark, and it's a big disappointment. We should also have been better with David, but he was blocked by Fernando when he came out from his second pit-stop, which destroyed his chance. Congratulations to Renault - they won the race so well done to them."
