Red Bull boss backs Vettel
Red Bull owner Dietrich Mateschitz insists reigning world champion Sebastian Vettel will be even stronger in 2012.
Vettel successfully defended his Drivers' Championship title last season but the likes of Ferrari, McLaren and Mercedes are keen to challenge Red Bull for honours in the coming campaign.
Ferrari's Fernando Alonso and McLaren pair Jenson Button and Lewis Hamilton have all voiced their optimism ahead of the 2012 Formula 1 season, with all three predicting they will be able to close the gap on Vettel.
Vettel finished over 100 points clear of nearest rival Button last season and Mateschitz says he expects the German to continue to dominate.
