Red Bull's Mark Webber has singled out Ferrari as Formula One's team to beat, with Felipe Massa repaying the compliment but hoping the Australian was right.
Sauber's Sergio Perez was quickest on the third day of the final pre-season test in Barcelona although the Mexican's best lap time was a low fuel qualifying simulation on super-soft tyres.

Webber was third for the world champions.

the season opens in Melbourne in just over 2 weeks.
