Ferrari boss Stefano Domenicali believes Red Bull Racing's Sebastian Vettel is not 'unbeatable', despite the German's current form.

Vettel was in a class of his own throughout the weekend in India and topped every single session at the Buddh International Circuit, en-route to his fourth victory in succession, something that saw him increase his increase his lead in the drivers' championship from 6 points to 13. While Ferrari number one driver, Fernando Alonso did lose ground though, Domenicali hailed his drive through to second place and promised that the Scuderia will continue to fight on in the remaining three events.

"What a race that was from Fernando, simply amazing! Yesterday, he'd said he would tackle this race like a sixty lap qualifying session and he was true to his word: on the attack from start to finish, the only one from the top ten on the grid to make up places by the end," Domenicali reflected after the 17th round in the 2012 F1 World Championship.

"This second place is all down to his talent, to his aggressive approach and the fact he never wants to give up, backed up by a team that is doing the maximum to give him a car that is worthy of him.

"Sure, we leave India with a bigger gap to the leader of the Drivers' championship than when we got here, but this race should not leave those who are ahead in a calm and relaxed mood.

"Fernando and Ferrari will not slacken their efforts by a centimetre, right to the end of this long season."

"There are three more finals to go, up against very strong opponents, but they are not unbeatable," he added.

"I recall that, in 1982, the Italian football team was definitely not the strongest but went on to win that year's World Cup. We believe in our chances and I'm sure that so do all our fans!"

Ferrari technical director, Pat Fry meanwhile was equally impressed with Alonso's performance, although he conceded that the Maranello-based outfit must do better in qualifying if they are to stand a better chance of beating Vettel and ultimately winning.

"Fernando produced yet another amazing performance in what has been an incredible season for him: finishing second having started fifth in a race where overtaking moves are a rare commodity, despite the double DRS zone is really an encouraging sign," Fry continued.

"We must, however, improve the performance of our car in qualifying and that's why we are working flat out to bring some updates to every race from now to the end of the season. If we manage to get our drivers further up the starting grid, then we can put Red Bull under pressure: at the moment, Sebastian Vettel is flying away too easily, leading from the start.

"We know we can count on a really great driver and, alongside him, we will fight right to the end in Brazil."
