Pastor Maldonado has expressed his delight after qualifying on the front row of the grid for Sunday's Singapore Grand Prix.

The Williams driver posted a stunning 1 minute 46.804 second lap at the Marina Bay Street Circuit to put himself in contention of scoring points for the first time since his maiden victory in Spain this year.

Maldonado admits the team were struggling for pace on Friday but is pleased with the turnaround: "We've been working really hard as at the beginning of the weekend we were struggling for pace," he said.

"We continued improving throughout qualifying and we found a good balance in the car. I then had to put together a good lap in Q3 and I knew we could be right up at the front.

"I'm really looking forward to the race as we've shown consistently good pace on our longer runs throughout practice. We have all the tools to be competitive tomorrow, so it should be a good race for us."

Bruno Senna in the sister Williams had a highly contrasting afternoon to Maldonado after twice colliding with the barriers. The Brazilian will start 17th on Sunday, something he admits is far from ideal.

"I was pushing very hard to get a good lap [in Q2] but I pushed a little over the edge. This place isn't very forgiving so we broke the rear suspension," Senna said.

"It isn't easy to overtake here but we've raced from the back before. I'm going to need to push really hard to get some points out the race tomorrow."
