The appearance of managers Steve and David Robertson was all the more notable given Raikkonen's participation thousands of miles away in the Welsh rally.

And Turun Sanomat newspaper reports that they watched the grand prix from within Williams' hospitality area.

The signs are growing stronger every day that 32-year-old Raikkonen is definitely motivated to return to the sport that gave him 18 wins between 2001 and 2009.

Sir Frank Williams finally confirmed to the Finnish broadcaster MTV3 on Sunday that his Oxfordshire based team "has strong interest" in housing Raikkonen next year.

"Obviously, anyone worth his salt in any business will argue about the price of things," he grinned, "so there is an argument going on, which of course is quite normal.

"I must choose my words carefully by saying only that it (Raikkonen coming to Williams) is possible."

And team co-founder Patrick Head confirmed in Abu Dhabi that Williams' interest in the former McLaren and Ferrari driver is not new.

"We were interested in Kimi when he drove for Sauber," the Briton is quoted as saying. "We proposed to our then partner BMW to make him an offer but they thought it was too much money."
