Lewis Hamilton has not won the Brazilian Grand Prix in 10 attempts, and has just one pole position to his name at Interlagos. It's the only track on the current calendar, barring new arrival Baku, where he hasn't tasted victory.
The question is, does that mean anything at all on what is another must-win weekend for Hamilton, or is it just a coincidence? After all, if he doesn't win, chances are Mercedes team-mate Nico Rosberg will. And if Rosberg wins, he's world champion.
Based on what we saw during Friday practice at Interlagos, there's not much for Hamilton to be worried about. Save, of course, for the fact that the gap from Mercedes to the rest suggests there less chance of any of its rivals getting involved in the battle for the top two positions.
