Red Bull Formula One driver Mark Webber said rival Fernando Alonso of Ferrari has a good chance of bagging the title over his teammate Sebastian Vettel.
"I think Alonso has a good chance of winning the title. He had a couple of tough races like Suzuka (Japan) where he lost points. But with four races to go both Sebastian and Alonso have many points left to bag. It is still very open," said Webber at a promotional event here.
"Both of them have had a tough time but they have been very consistent too. Anything can happen. We could have a wet race in Brazil. It's not over till it is over."
Talking about his own performance through the season and his current target, Webber said: "I would love to win races and improve my position on the championship table, as much as possible. Our goal is to challenge for victories and we are capable of doing that.
"We have a good lead in constructors' championship. Everyone is putting in massive amount of work and if we can win the constructors' title three years in a row, nothing can be more satisfying. It will be a special achievement for everyone involved in the team. We need to focus on the next two races maximise our potential."
