SINGAPORE, Malaysia - After arriving in Singapore for the 2012 Singapore F1 GP fresh from a third podium place of the season in Monza two weeks earlier, Sauber's Sergio Perez hasn’t revealed much about his F1 future.The 22-year-old Mexican has shown plenty of promise in his second season at the elite level with his second-place finish in Italy, fuelling speculation about a move to a bigger team.FERRARI FUTURE?As Ferrari mulls over Felipe Massa's future, many believe Perez is in prime position to join championship leader Fernando Alonso at the Italian outfit for the start of the 2013 campaign.Paddock rumours linking Lewis Hamilton with a switch from McLaren to Mercedes have also opened the possibility of a spare seat at the British team but Perez played down talk of this. "In my position, when I score good points, the rumours start... if I have a bad race, the rumours go away and the media chase another driver who has a good result."In that respect, I am not worried. I know I have a very strong car for the next seven races so I just hope to deliver a strong performance."Perez's performances have lifted him to ninth in the standings on 65 points, ahead of Massa and seven-times World champion Michael Schumacher, but, when pressed about whether he had been contacted over a possible move, his response was short and to the point."There have been no approaches from any teams," he said.OPINION RESPECTEDThe Ferrari Driving Academy member's hopes of an early step up to the prestigious Italian outfit were recently dealt a blow when the team's chairman Luca di Montezemolo said Perez lacked the necessary experience to join Alonso."I fully respect his opinion. I have to know my position; probably, he means to become a Ferrari driver you need more... I don't know... because it's only my second year in F1," Perez said. "I feel ready to do a good job, to be in a top team, to be able to fight for the title, for the championship, but I fully respect his opinion."Regarding McLaren, there have been many rumours, before it was Ferrari and now it is McLaren. My most important thing is to keep doing a good job and try to maximise my car's potential for the next seven races."
