VALTTERI Bottas is looking forward to one of the most challenging weekends in the Formula 1 season as they head to Singapore.

The night race around the Marina Bay street circuit is unlike any other on the calendar.

It is also an important race for Grove’s Williams team, who are only three points ahead of fifth-placed Force India in the constructors’ standings.

Bottas, who finished sixth in the Italian Grand Prix earlier this month, is braced for a taxing few days.

The Finn said: “That track has so many corners, so as a driver to complete the perfect lap in Singapore it’s quite tricky, but it’s really rewarding when you do.

“Personally, I do like the challenge.

“It’s a night race and in terms of how much you need to focus, it’s probably the most difficult track after Monaco – there’s no room for mistakes.”

Teammate Felipe Massa said: “It’s very humid and so hot.

“That said, I really enjoy racing there and it’s a very rewarding track.

“It’s always a good feeling racing in Singapore.”
