Hamilton fears he cannot trust German teammate

Lewis Hamilton revealed on Monday he may not be able to trust his Mercedes teammate, Nico Rosberg, in their future on-track duels for the drivers' world title.

The 29-year-old Briton, who was forced to retire from Sunday's Belgian Grand Prix after suffering a puncture when Rosberg drove into him on the second lap, said he was uncertain how to approach the next race, the Italian Grand Prix at Monza on Sept 7.

He claimed Rosberg said he had deliberately hit him 'to make a point' but the German, who now leads the title race by 29 points, said it was only a racing incident.
