Jacques Villeneuve has said he is rooting for Fernando Alonso to win the F1 title this season, as while Sebastian Vettel is also an 'ace', the German still has a lot of maturing to do.

Villeneuve's comments come ahead of this weekend's inaugural United States Grand Prix at the Circuit of the Americas, the penultimate round in the championship, and while Vettel does lead Alonso in the drivers' championship and is the favourite to claim the crown given the superiority of the Red Bull RB8 over the Ferrari F2012, JV is adamant Alonso is the better and more 'deserving' driver. Indeed Villeneuve reckons Vettel is still a bit of a kid who spits out his dummy when things go wrong.

"I have no doubts, Fernando Alonso is the best, that's why I root for him," Villeneuve confirmed to Autosprint magazine. "Seb is super quick but there is a difference with Fernando that emerges in the case of an unfavourable situation.

"Alonso remains calm, cool, and rational, while Vettel most times gets upset, angry, screams and flicks the middle finger. He reacts like a child. These behaviours indicate two different states of maturity.

"But let's be clear, Sebastian is an ace, too. However, he struggles more in critical situations. He looks almost unbeatable when he leads but if he needs to catch up he becomes vulnerable."

The former Williams driver also that Vettel's drive in Abu Dhabi wasn't that amazing either, even though the Red Bull pilot stormed back to finish third, despite having to start from the pit lane.

"For me, it confirmed what I think about Vettel," explained the 1997 F1 world champion. "These are facts - while recovering from the back he first got in contact with [Bruno] Senna, who was ahead of him, and damaged his front wing. Then he lost control of his car and crashed under the safety car. A very serious error that had light consequences. As for the rest, he was super quick.

"But he was lucky and I'm not changing my mind. Alonso deserves the 2012 title more," JV concluded.
