Nico Rosberg has tipped former Mercedes team-mate Lewis Hamilton to scoop a sixth Formula One world title this year – although he believes some subtle regulation changes could lead to a few surprises.
Hamilton won eight of the final 11 races as he collected his fifth world crown last year, equalling Juan Manuel Fangio's haul and moving to within two of Michael Schumacher's record.
Rosberg, the last driver to get the better of Hamilton in 2016 before promptly retiring, expects the likes of Sebastian Vettel and new Ferrari team-mate Charles Leclerc and Red Bull's Max Verstappen to be strong contenders.
