"The big mover today has been Valentino who has jumped nine positions up the leaderboard to 15th," highlighted Stobart VK M-Sport Ford team principal Malcolm Wilson. "It is fantastic to see his pace has improved as he is now getting used to the conditions."
"I'm really enjoying this rally and I have settled in more than the first day," confirmed Rossi. "The Focus feels very good now and my times are improving with every stage and that was my main aim for this rally."
Rossi heads into the final day almost exactly one-minute behind 14th place and nearly five minutes behind tenth position (held by team-mate Matthew Wilson).
That means the #46 will almost certainly need to benefit from retirements ahead of him if he is to better his eleventh place finish on his previous WRC appearance, during the less challenging 2006 Rally of New Zealand.
Nevertheless, Rossi is on target to finish much closer to the rally winner than he had been in NZ. The eight-time world champion was 20min 38.8sec behind Marcus Gronholm in 2006, but he is presently only 9min 37.6sec behind Rally GB leader Jari-Matti Latvala.
The 2008 Wales Rally GB concludes with four new stages on Sunday - and the warning of further wintery weather overnight.
"Tomorrow will be a very difficult day judging by the weather forecast, but hopefully the Stobart crews will all make it to the finish ramp," said Wilson.
