Lewis Hamilton plays down Nico Rosberg 'friction' before Bahrain GP

Mercedes driver Lewis Hamilton acknowledges the "friction" between him and team-mate Nico Rosberg, but insists it "very rarely comes from his side" as he prefers to do his talking on the track.

In China the German accused Hamilton of deliberately driving slowly to back him up into the chasing Ferrari of Sebastian Vettel.

Redbull's Daniel Ricciardo heads into this weekend aiming for a top five spot so his team can take some big steps forward.
