Piquet admitted his second place in Germany was lucky

Formula One driver Nelson Piquet Jr, of the Enstone-based Renault team, says another podium finish is unlikely at the Hungarian Grand Prix on 3 August.

The Brazilian driver finished second in Germany but remains cautious.

"I think it will be difficult to fight for another podium under usual circumstances because the gap to the leading cars is still too big.

"I think the realistic goal is to fight for some points on Sunday, and if we can do that I will be very happy."
