"The start of the rally, in very awkward conditions, was fairly difficult for us. Due to a problem that was beyond the team's control, we were unable to use the gearbox and differential settings that had been validated during our tests. M-Sport did everything possible to help us find the best compromise, but it still meant we had to make do with a less than optimal solution, particularly in the slippery and treacherous conditions of the first day."
