Mercedes boss Toto Wolff has insisted that champions Red Bull will still be the team to beat this season despite their disastrous time in testing.
Red Bull had a disastrous time in Jerez, Spain - on two of the four days their car broke down without completing a lap.
However, the Mirror reports that Wolff said that he is sure that Red Bull will again be the pace setters this season as they have an outstanding driver in Sebastian Vettel and they have put together a group of people that work very well, plus they have resources from the parent company.
But Wolff played down claims his Mercedes team are championship favourites after one successful test in Jerez, in which Mercedes covered ten times the distance of Red Bull's Renault motors during the debut of the new engines.
