Enstone-based Renault F1's two-time world champion Fernando Alonso has expressed concerns over the effects bumps at one of the turns might have at this weekend’s Singapore Grand Prix.

The Spaniard is worried cars may suffer damage at a tight chicane on Turn 10 on the Marina Bay street circuit, which hosts the first night race in Formula One history.

The FIA are investigating the problem but Alonso believes it will be difficult to rectify the issue in time for today’s first practice session.

“It is not the best solution they could find I think,” he said.

“We worry that if we miss the chicane you miss the line and have to go over the curves.

“It could damage the chassis or the damage the car at the bottom. If you damage one car its not a problem as you can take the T-car but if you damage two you go home.

“It is a concern at the moment but I don’t know what is a better solution and I don’t know if they are able to do it quickly.”

Like the majority of drivers, Alonso is operating on European time while in Singapore to ensure he is at his peak during the evenings.

Aside from filling his time watching films since arriving in the city-state on Wednesday, the 27-year-old has walked the circuit to ensure he faces no surprises this weekend.
