McLaren driver Jenson Button believes that the Formula 1 title will be won by either Fernando Alonso or Sebastian Vettel.
The Ferrari racer has led the championship for most of the season, although Vettel's victory in the Singapore Grand Prix on Sunday has cut Alonso's lead to 29 points.
Button, who finished second in Singapore, believes that teammate Lewis Hamilton's retirement from the race has all but cost him his chances of the title.
"It's hard for anyone [to catch Alonso] except Seb at the moment," Button said. "It's between those two but there's still a lot of people with a long shot. That's what we're all going to go for.
"It just shows one bad race makes a massive difference. Fernando had his in Spa, Lewis had his in Spa and here, Seb had his at the last race.
"I had mine in the last race. When no-one has the consistency you can't close a big gap on someone. Seb is only 29 points behind, that's a gap that's shrinking."
The next race is the Japanese Grand Prix on October 7.
