Meanwhile, Peugeot UK's Kris Meeke, the outgoing IRC champion and last year's Sanremo winner, thought he'd done enough for third place only for Freddy Loix, in the third factory Fabia, to beat his time on the final stage and take third place by 4.2 seconds.
"I did not have the best feeling with my car like I had on the other rallies and the poor road position I was given for the first five stages made it very difficult. To take third is a good achievement," Loix stated.
Bryan Bouffier dropped out of fifth place when he picked up a front-left puncture on stage eight and lost more than three minutes after initially attempting to drive through the test with the flat tyre before stopping to change. He eventually made it home in 12th.
Guy Wilks started day two in 12th overall after losing time on Friday's final test by selecting a wet weather tyre in the mistaken belief that the road would be damper than it was. However, the Skoda UK Motorsport driver's challenge ended after seven kilometres of Saturday's first stage when he slid into a low wall and damaged the left-rear corner of his Fabia S2000 to the extent he was unable to continue.
Behind Rossetti, Kopecky and the unfortunate Basso in fifth, sixth and seventh, Thierry Neuville landed the final IRC drivers' point in his Team Peugeot Belgium-Luxembourg 207 following a mature drive, which culminated in him demoting Italian veteran Gianfranco Cunico on the final stage. Cunico won in Sanremo in 1993 and admitted he is still acclimatising to his 207, which he was using for a second time.
Peugeot Sport Portugal's Bruno Magalahes completed the top 10 on his return to the IRC after missing the last round in Czech Republic. With limited experience of the various tyre compounds available to him, it was a strong performance by the 30-year-old.
Local hero Sandro Sottile won the IRC 2WD Cup in his Honda Civic Type-R, while Briton Harry Hunt bagged his second points of the season in seventh place in his Fiesta R2.
The IRC now continues in three weeks time, with the RACMSA Rally of Scotland, running from October 15-17.
