Rumours that Kamui Kobayashi is heading to Pirelli have proven untrue with Jaime Alguersuari and Lucas di Grassi retaining their test driver roles.
On Wednesday Tweets emerged claiming that Kobayashi, a regular favourite with those who like to bet on F1, and who was left without a race-seat for 2013 after being dropped by Sauber, would take up a role as a Pirelli test driver.
However, this proved to be incorrect as Pirelli's motorsport director Paul Hembery revealed that the Italian tyre manufacturer would not be altering their test driver line-up.
"I read on Twitter that [Kamui] Kobayashi would be unveiled as a test driver, but he won't," said Hembery.
"There is no reason to change what we have. We have had a great time with Jaime Alguersuari and Lucas di Grassi."
Bookmakers like Paddy Power are still offering odds on Kobayashi joining a new team before the start of the start of the new season.
