Fernando Alonso has backed Ferrari to fight back in the final races of the F1 season after a disappointing weekend on track in Singapore.

Alonso had gone into the weekend looking to extend his run of podium finishes in the annual night race to four, but instead trailed in nearly a minute behind winner Sebastian Vettel in fourth place.

It was a result that means the Spaniard is now out of the title race with five races to go but he vowed to help Ferrari fight back into a position where it can challenge for victories again before the end of the season, despite technical director Pat Fry having admitted that the team was now the 'third fastest' on the grid [See separate story HERE].

"When you see that the entire team is doing its utmost and maybe even more, you can only be satisfied," he reflected. "Obviously, we hoped for better here, but I have great faith in the work we are doing. We were convinced we could make a step forward after the summer break, but it did not turn out that way, while our rivals progressed even more.

"That does not mean we cannot be in the fight in the next few races: it will be tough, but I can feel the team has a great wish to redeem itself and to prove its worth. It is this type of attitude which, last spring, convinced me to extend my contract to the end of 2016. If I did not believe in the quality and determination of the people and the potential in terms of the structure and resources, then I would not have made that decision.

"Now we must knuckle down after a difficult weekend and prepare as well as possible for the race in Suzuka, one of the greatest tracks on the whole championship calendar."

Alonso sits third in the championship standings, a point behind Jenson Button and two ahead of Mark Webber.
