Vettel on 'messy day'

World champion Sebastian Vettel says Red Bull's second day of testing in Barcelona was "messy" following a session interrupted by a mechanical failure and eight red flags which left the German unable to find a "good rhythm".

Vettel also reveals he is looking forward to receiving some upgrades for the final two days of testing before the season begins in Australia on Sunday 18 March, and admits " it is hard to judge whether you are quick because people play around with fuel loads".
