Jul.19 (GMM) It is not yet necessary for Ferrari to appoint a number one driver for the rest of the 2008 championship, according to Felipe Massa.

The Brazilian and his teammate, reigning world champion Kimi Raikkonen, are currently tied on points at the top of the drivers' standings with McLaren rival Lewis Hamilton.

Massa told the French morning newspaper Le Figaro: "The team does not have to make a decision as long as things are not leaning either one way or the other."

In previous years, Michael Schumacher was the undisputed number one driver, receiving the balance of the Italian marque's effort to lift the drivers' crown.

But Massa said last year he was also on equal terms with Raikkonen, until his chances took a final hit at the Italian grand prix.

"From then on, there remained a small chance for Kimi. To help him to do it, the team did everything for him, myself included.

"This time I hope it will be my turn."

In the interview, Massa also played down suggestions Ferrari may be able to vacate his seat in the near future -- perhaps by means of performance clauses.

"No. I have a contract until the end of 2010 and I feel perfectly comfortable in the team," he insisted.
