May 1 (GMM) Renault sporting director Steve Nielsen is hopeful that team rookie Nelson Piquet can put his troubles behind him when the formula one season resumes in Turkey next weekend.



After a difficult start to the season, the 22-year-old Brazilian looked to have closed the gap on his teammate Fernando Alonso at Barcelona last weekend, as he made the 'Q3' section of qualifying for the first time.



But in the Spanish race, Piquet spun off and then collided with Sebastien Bourdais' Toro Rosso while trying to regain lost places.



"I would say it was Bourdais' fault but the problem is that Nelson shouldn't have put himself so far back," Nielsen said.



"As it is, he's still to deliver a really good race for us, and hopefully he will do that next time," he added.
