Christian Horner, Red Bull Racing team boss says that McLaren’s Jenson Button is the biggest challenge in the 2012 F1 season. And he is confident that Vettel had an unbelievable year and in the end dominated significantly.
“Seb had an unbelievable year and in the end dominated significantly,” Planet F1 reported, Horner told BBC Radio 5 live.
“But there are some big opponents out there, with six World Champions on the grid.
“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.”
When pressed for who – aside from Webber – he expected to provide the biggest challenge, Horner responded: “Probably Jenson.”
