Bruno Senna heads to this weekend's Belgian Grand Prix at Spa-Francorchamps hoping to maintain the form that saw him finish seventh in Hungary - and earn fulsome praise from the Williams team - prior to F1's summer break.

Although he has enjoyed better results this season, the Brazilian's drive from ninth on the grid completed his strongest all-around performance since joining the Grove squad, and thrust him firmly back into discussions about next year's driver line-up, having previously been thought the best candidate to make way for test and reserve driver Valtteri Bottas. New CEO Toto Wolff admitted earlier this week that it would now be easier to field three cars than make a choice between the contenders - which also include Spanish GP winner Pastor Maldonado - but Senna remains focused on carrying his form through into the second half of the season.

"We've had a good streak of races recently, and I had a solid result in Hungary, so I'm looking forward to keeping the momentum going," he said before setting off for Belgium, "Spa is one of my favourite tracks and I raced there last year with the Pirelli tyres so that knowledge will help with our performance this time around. Qualifying will be important and I'm looking to get into Q3 like I did in the last race and, from there, hopefully scoring some good points for the team."

Like Senna, Maldonado has tasted success at Spa in the past, and arrives at the Belgian venue hoping to add to his championship tally for the first time since surprising the F1 field with his victory at the Circuit de Catalunya.

"Spa is a very special circuit for me because I've had a lot of success there in the past and I really enjoy the layout," the Venezuelan confirmed, "The circuit also has a lot of history, so it's a race that you want to do well at. It will also be interesting to see the performance of the other teams and find out who has made gains since we last raced. I'm looking forward to getting going again after the summer break and, hopefully, we can build on the good progress we've shown so far this season and have a strong run of results in the second half of the year."

Chief operations engineer Mark Gillan has said that the team expects to be greeted with some typical Ardennes region rain at the start of the weekend, but remains confident that conditions will be more favourable as the weekend progresses.
