F1 pundit Johnny Herbert believes that Jenson Button and Kimi Raikkonen will be the drivers to watch in 2013.
While Button endured a disappointing 2012 season, finishing fifth in the Drivers' standings, 93 points behind World title winner Sebastian Vettel, Herbert feels that the tide could change for the McLaren driver in 2013.
"McLaren and Jenson Button. [He's] leading the team and I think he's got a good situation to be able to possibly win that second world title," Herbert told Sky Sports.
The Briton is not the only former World Champion that Herbert thinks will surprise, with the ex-Benetton driver backing Kimi Raikkonen to build on a successful comeback year.
"I think it was fantastic for him. The comeback has been absolutely brilliant," he said.
"He's come back, he's very, very hungry for it. We saw the race win and, potentially, he could be a big threat next year."
