Friday 28 March at 09:07 : A former Ferrari team boss has advised the Maranello based squad to consider a couple of current drivers should a vacant cockpit arise in the future.

"I would not want to be in Felipe's skin -- two big weekends, three big mistakes," said Cesare Fiorio, who led the Prancing Horse nearly twenty years ago before the ultra-successful Jean Todt era.

Amid intense speculation that error-prone Felipe Massa's seat beyond 2008 is in doubt, Fiorio acknowledges rumours that Sebastian Vettel might be a good candidate.

"Although I am convinced that the young German has great potential, there are two drivers on the market who would be a guarantee of success," Fiorio, 68, told the Italian magazine Autosprint.

He said he is referring to Fernando Alonso, and BMW-Sauber's Robert Kubica, two drivers whose current contracts allow them to leave their respective teams at the end of this year.

Fiorio, who also worked with the Prost and Minardi teams following his Ferrari career, is also a great supporter of Jarno Trulli, the Italian driver who powered his Toyota to a laudable fourth place in Malaysia last weekend.

He thinks the 33-year-old is "experienced enough to bear the burden" of being an Italian at the wheel of the country's revered marque.
