Singapore's bid a 'massive jigsaw puzzle'.

Plans for Singapore to hold a round of the FIA Formula 1 World Championship is still very much a 'work in progress' according to Michael Roche, the man who heads the feasibility study team into plans for the country to hold a grand prix.

Speaking to Malaysia's New Straits Times he confirmed that it is a 'massive jigsaw puzzle' at the moment, and that they are still trying to overcome several potential problems.

"We don't have the luxury of space in an island city state. That is always the big challenge -- trying to make it feasible," he told the 'paper.

"They've improved a lot of the road systems. A lot of land has been reclaimed, giving us the luxury of being able to create a pit area. But nothing has been confirmed yet.

"The reason we're hesitating is that it's such a massive jigsaw puzzle. Each time we think we've overcome an obstacle, we lift up the stone and there are other issues and obstacles."

Asked whether Singapore would replace Malaysia on the schedule, particularly in light of the fact, Formula 1 boss, Bernie Ecclestone has recently said the Sepang circuit is looking a 'little shabby', Roche noted that that is not the case. Indeed in his view the Malaysian GP and one in Singapore could compliment each other very well and would work well run back-to-back.

"It's not our intention to come to any country to take a race away. We've worked with Ecclestone for a long time to bring this about," he added in the same article.
