It's not every day that Formula 1's reigning world champion describes a rival driver as "a force to be reckoned with", but that's exactly the phrase Lewis Hamilton used to describe Max Verstappen after the British Grand Prix.
F1 is becoming used to star performances by the Dutch teenager, and here was yet another to add to the growing catalogue - putting what remains a lesser car in the Red Bull-Renault RB12 in between the two dominant Mercedes, and showing Nico Rosberg the way for a long spell in wheel-to-wheel battle.
Rosberg has not generally shown himself to be among F1's absolute elite in this regard, but he is a veteran of 195 grands prix and was driving a car Hamilton said Mercedes estimated to be 0.5 seconds per lap faster than the Red Bull in race trim.
