Red Bull's Daniil Kvyat headed Mercedes drivers Nico Rosberg and Lewis Hamilton in a wet Japanese GP second practice.

The Russian beat Rosberg by just 0.023 seconds, with the world championship leader a further 0.553secs adrift.

Red Bull's Daniel Ricciardo was fourth ahead of the Ferraris of Sebastian Vettel and Kimi Raikkonen, all three having off-track moments in the rain.

More than 140,000 fans are expected to attend the race on Sunday.
