Melbourne: Four-time world champion Sebastian Vettel Thursday played down fears he could fall out with new team-mate Kimi Raikkonen after his big switch to Ferrari this season.

Vettel moved from Red Bull, where he struggled behind Australian Daniel Ricciardo as Mercedes romped away with both the drivers and constructors world titles last year. The German has had trouble in the past with team-mates, notably Australian Mark Webber, but he does not believe there will be any issues with the sometimes surly Raikkonen.
