PALMER: What's happened to Perez's precision race craft?

Sergio Perez had a tricky weekend in Japan, getting involved in a couple of incidents, incurring two separate penalties, and even retiring from the race – twice.

The problem started for Checo on Saturday. His Red Bull team mate Max Verstappen turned up to Japan on another level to anything we’ve seen already this season. He’s wiped the floor with everyone for most of the year, but having been beaten in Singapore it seemed he was ready to crush the opposition in revenge – and that started from the very first lap of practice on the hard tyre.
