Horner tips Hamilton as man to beat despite Rosberg surge

Red Bull team principal Christian Horner tips Lewis Hamilton to also win a third title on the trot, even though it was the Briton's teammate Nico Rosberg with the strongest form late in 2015.

"How high was Lewis' motivation in those last few races?" Horner wondered.

"He's had a winter off to go away and reflect. With successive championships, he absolutely starts the season as the man to beat."
