M-Sport Ford will work hard to rectify some technical issues that plagued their cars at WRC Rally Corsica and left four-time world champion Sebastien Ogier frustrated with the lack of progress.

A disgruntled Ogier suffered intermittent electrical glitches on the final day and fell away to finish nearly a minute off winner Thierry Neuville while holding off third-placed Dani Sordo by just 1.3 seconds.

"A few too many technical problems for us, not only on our car but also on both our team-mates' cars so that's definitely something the team has to work very hard on," said Ogier.

Despite the setback the Frenchman still leads the World Rally Championship.
