MARINA BAY, Singapore - Much like at the Italian F1 GP, the 2013 "silly season" buzzing in the paddock ahead of this weekend's Singapore race.Sergio Perez was asked if, having been turned down by Ferrari president Luca di Montezemolo, there was any truth in the speculation that he is now near the top of McLaren's short-list to replace Lewis Hamilton."Before it was Ferrari,." the Mexican said, "now it's McLaren. Always when I have a good race, the media put me in a different team."'WE'LL SEE WHAT HAPPENS'Another contender for Hamilton's seat, should he jump ship to Mercedes, is former McLaren driver Kimi Raikkonen. Raikkonen, currently at Lotus, is not even committing to the sport at present: "You never know. There are a lot of other nice things to do than F1."We have options - we'll see what happens."According to F1's rumour sages, the 2007 champioin is no longer considered a serious contender to replace Felipe Massa at Ferrari. Some believe Force India's Nico Hulkenberg is favourite for that job.Hulkenberg said: "There is a good chance I will be with Force India in 2013 but nothing has been announced."Alonso wants to keep Massa alongside him: "If the team decides to change Felipe, someone who arrives would have to be better. Looking at all the names the media have been putting forward I'm not sure if you realise quite how much Felipe has achieved in F1 compared to them."
