Fernando Alonso has given his backing to Felipe Massa as the Brazilian seeks to retain his drive with Ferrari for the 2013 F1 season.

Massa's future has been in doubt for some time after a series of below-par performances, leading to a various names being linked with his seat when his current deal expires at the end of the year.

However, speaking in Singapore ahead of F1's annual night race this weekend, Alonso said the people being mentioned in relation to Massa's drive weren't up to the job of replacing the Brazilian and that if Ferrari were to look for someone new, they would have to be stronger than Massa.

"I think we need to respect that the team will make a decision," he said. "In my opinion we need a driver that will respect Ferrari and respect the tradition that here, we work for the team and for the red cars. This is the first priority.

"Second, I have been working with Felipe for three years now with a very good relationship and if the team decides to change Felipe, the person that arrives has to be better than he is. All the names and all the things written - I don't know if they are written with the head or with the heart. All the names you hear, I don't know if you can compare them to what Felipe has done in Formula One and what these little names have done."

Massa himself said earlier this weekend that good results were key to his future.
