SAO PAULO, Brazil - Sergio Perez says he is "95% sure" he will still be on the F1 grid in 2014. The Mexican has lost his McLaren seat but sounded confident about his future when speaking to reporters in the Interlagos paddock.There was some doubt the 23-year-old remained on good terms with his backers but Italian reports during the week claimed Perez was now on the market along with the sponsorship of Claro, a Mexican brand seen on the McLaren in 2013.Perez told F1's official website: "I'm pretty convinced that in a year I will probably tell you that it was the best thing that could have happened to me, to leave McLaren."'95% CHANCE'Asked to nominate his hopes in a percentage, Perez answered: "Ha, 95% I will remain in F1 - but the remaining five per cent is always tricky. From my gut feeling I am pretty sure I will race in 2014."Asked if his options were Sauber and Force India, he insisted: "It's not only them. There are quite a number of options and I can say right now it is looking better than it was looking a week ago."A rumour in the Interlagos paddock on Thursday even linked Perez with Lotus. "There are always rumours around," he responded, "and rumours sometimes go faster than the cars." Stay with Wheels24 for the 2013 Brazilian GP weekend.
