Red Bull boss Horner feels Button is a threat

Red Bull boss Christian Horner said on Wednesday that the biggest threat to his team in the upcoming F1 season was from McLaren's Jenson Button.

Although Horner felt that Lewis Hamilton (McLaren), Fernando Alonso (Ferrari)and Kimi Raikkonen (Lotus) are also worthy contenders, the 32-year-old Button was tipped to be the driver with the maximum ability to threaten defending champion Sebastian Vettel. "Lewis is going to be pushing hard this year, Jenson had a great year last year, you can't rule out Fernando because he is a world-class driver and it will be interesting to see how Kimi fares on his return," Horner was quoted as saying by BBC.

When asked to pick one from the list of drivers who is most likely to provide the stiffest competition, Horner chose Button. The Briton finished second to Vettel in the 2011 season although he was a distant 122 behind the German.

Horner also had a word to say on Vettel. "We are yet to see the best from him. He will evolve and get stronger."
