Strong line-up for Macau

Drivers from the British, Japanese, Asian, Spanish and Italian championships have all entered this year, along with the front-runners from the Euro Series.

Unlike last year, the race should enable the British and Euro Series champions to go head to head as well. Last year, Alvaro Parente and Lewis Hamilton both skipped the event.

2006 British F3 champion Mike Conway is competing with Double R Racing though, and is confident after having a strong run last year with Manor Motorsport, who won the race with Lucas di Grassi.

"Knowing the circuit is key to success here," he said. "From my experience last year I know that it takes a couple of practice sessions to get up to speed."

While the Euro Series championship still isn't decided, title contenders Paul di Resta and Sebastian Vettel are both entered for the race.

However, di Resta might not make the trip for the end of season showpiece.

"Lots of people have told me I'm on the entry list, but I haven't been told I'm definitely doing it," he told autosport.com.

It is possible that his ASM team have entered a car for the Scot on the off chance of him doing the race, because it would be difficult to get a late entry.

Di Resta added: "It would be nice to go there, but people go there to achieve something, and with it being my first year I would be under less pressure on that side of things."
