"On a day of biblical storms, with dramatic forks of lightning spearing out of inky clouds, there was the first hint of potential tension between Mercedes team-mates Lewis Hamilton and Nico Rosberg at the Malaysian Grand Prix.

"Did Rosberg effectively force Hamilton to back out of a qualifying lap? Hamilton said no; Rosberg said it was not a relevant question. But the German was undoubtedly sensitive to the accusation. The fact Hamilton took pole anyway took much of the tension out of it, and he was able to rise above any controversy.

"Opinion was split in the paddock, but the incident can only add spice to the dynamic of their continuing battle, which will be rejoined in the race this afternoon."

Nico Rosberg might live to regret a few words he said after the Australian Grand Prix - he wanted a fight from the Ferraris and it looks like he has certainly got one.

Vettel was just 0.074 seconds off Hamilton's pole-securing time and that, along with their promising long runs in practice, suggests they may be more than just "the best of the rest".

But it is not just the Ferraris Rosberg and Hamilton have to be wary of, as Saturday also provided us with the first hint of an intra-team battle...

Hello! It is race day at the second grand prix of the season - the Malaysian GP.

Lewis Hamilton goes on the hunt for a second successive victory at the front of the pack, having secured pole in Saturday's rain affected qualifying.

However, for the first time in 10 races, it is not his Mercedes team-mate Nico Rosberg alongside him on the front row, instead it is Sebastian Vettel.

The Ferraris have turned up to the party.

Nico Rosberg wanted a fight, and it looks like he has got it. Question is, which will prove to be the bigger one today?

The fight from within...
