Red Bull not fooled by Daniel Ricciardo's Canadian GP F1 win

Daniel Ricciardo's maiden victory last Sunday was also Red Bull's first win of the 2014 F1 season.

But the opportunistic nature of the triumph, which was only possible after Mercedes duo Nico Rosberg and Lewis Hamilton hit trouble, has not left Red Bull under any illusions about the task it still faces if it wants to win the title this year.

Red Bull boss Christian Horner said: "Let's not beat about the bush - Mercedes were the quickest car.

"They ran into their issues, whatever they were, and we have had issues at other points of the season. They were very, very strong.

"We still have a lot to do. We were 12-15 km/h slower compared to a Force India or Williams on the straight, and that is where we need to improve."

Although there is growing optimism that Red Bull can challenge Mercedes more at tracks that are not so power critical, Horner says there is still a "significant" way to go before it is on equal terms with its Brackley-based rival.

"You guys [the media] were asking at one point if Mercedes can win all the races. I said theoretically they could but in all probability they wouldn't," said Horner.

"What we have managed to do is keep chipping away.

"We have managed to improve the car, managed to improve the engine and we were there to capitalise on some misfortune for Mercedes.

"But we have to keep pushing and keep closing that gap down because it is still significant."
