Nov.8 (GMM) Roldan Rodriguez hopes to make the final step to securing a Force India race seat for 2008 at the Barcelona test next week.

The 22-year-old Spanish rookie has previously said he has an '80 per cent chance' of lining up on the grid for the Silverstone based team next year.

"I think I already have a foot and a half in the door," the GP2 driver confirmed to Spanish radio station Cadena SER, "but until it is really for sure, everything can change.

"I want to do a good job in the testing and make sure of my spot in the team," Rodriguez added.

To the Spanish sports daily Marca, meanwhile, he responded to those who believe his $15 million in private sponsorship is the real reason the former Spyker team is considering him for a seat.

"That is a normal thing that envious people say," Rodriguez is quoted as saying by the newspaper.

He also said McLaren's split with countryman Fernando Alonso ahead of next season is sure to hurt the British team.

"I think so. First Fernando helped Renault to grow, and then he did the same with McLaren," Rodriguez said.
