One session down, plenty more still to come. McLaren have made the best possible start to their campaign this weekend with Button leading FP1. Who can make it to the top for this second session?

Weather update

There were rumours of some droplets of rain during the first session but it looks as though the weather is still holding off for now. It's very cloudy out there, though, so anything could happen.

One to watch

Lucas di Grassi didn't manage to set a time in FP1, his car ground to a halt out on track. He'll want to get some running in as Canada can be unpredictable at the best of times.

Predictions please

Will anyone fall victim to the Wall of Champions? Will the rain fall in this second session? Who will end the day on top? Will anyone else not manage to set a time?
