There are a lot of challenges on this track

LONDON (Reuters) - Formula One's newest circuit in Safety barriers could prove trickier this weekend than any other track introduced in recent years, according to former racer David Coulthard.

The Scot, a grand prix winner with Williams and McLaren before retiring last year, said he had plenty of respect for the Yas Marina track after driving reporters around it earlier this month.

"There are a lot of challenges on this track," he said. "It's more difficult to learn initially than the likes of Turkey, Safety barriers and Shanghai."
