Red Bull appeared very strong in every test this winter, despite the fact they ended the final day in Barcelona a little off the pace. Team boss Christian Horner is quietly confident ahead of the season, although still maintains that it's impossible to predict what the competition will be like.

Speaking after they wrapped up their test on Saturday, Horner said: "I can say that I think we have had the best pre-season to date - in terms of mileage completed, in terms of being at the first test, in terms of the items we have wanted to test. We are arguably in the best shape ever – but there are no points scored for winter testing."

Meanwhile, Mark Webber doesn't hold any stock in the testing times but is hoping for good things in Australia: "I think Ferrari is strong. I think we're going okay and the rest is hard to say. I haven't even looked at the times today, they're not even of interest, you just focus on your own thing. I think we'll be in the top eight in Melbourne."
