Red Bull boss Christian Horner has voiced his concerns over the 'unhealthy' direction in which Formula 1 appears to be heading in the wake of another Mercedes one-two at the Australian Grand Prix.

The Brackley-based constructor picked up from where they left off last season by dominating the opening race of the season at Albert Park, building on their title success of 16 wins from 19 events in 2014 thanks to some steady driving from Lewis Hamilton and Nico Rosberg.

Horner has predicted more of the same throughout this campaign, calling on organisers to make changes to avoid similar two-horse races which could leave viewers switching off.

"Mercedes, take nothing away from them, they have done a great job and they have a good car, a fantastic engine, and two very good drivers," he is quoted as saying by the Daily Mail.

"The problem is the gap is so big you end up with three-tier racing and that's not healthy for Formula One. The FIA have the facts and they could quite easily come up with some form of equalisation otherwise I fear the interest will wane.

"I didn't see Mercedes much on the TV, and I can only imagine that's because it's not interesting watching a procession and the producer was looking to pick out other battles in the race."

Sebastian Vettel finished third on his Ferrari debut, a full 34 seconds off pacesetters Hamilton and Rosberg.
