Sergio Perez - Sauber 66SEOUL – Ferrari’s Fernando Alonso is confident he still has a strong chance of winning the title despite seeing his championship lead reduced.The Spaniard retired from the Japanese Grand Prix and race winner Sebastian Vettel is now only four points behind with a faster car.Alonso said: "I am sure we can be in the fight right down to the wire.”Alonso’s lead has been cut by 37 points in the last four races, in which period the Ferrari driver has retired twice.In the Belgian and Japanese Grands Prix, Alonso was involved in first-corner accidents - in Spa-Francorchamps he was hit by Romain Grosjean’s flying Lotus and in Suzuka on Sunday he got a puncture after a rear wheel was tagged by the front wing of Grosjean’s team-mate Kimi Raikkonen.But Alonso believes Ferrari are capable of re-establishing their advantage in the final five races, starting with the Korean Grand Prix this weekend."The people who are working on the car are the same who have done the job so far and there’s no reason to think they can’t do a good job again now,” he said.
