Risatti to deputise for Maldonado

Maldonado fractured his collarbone in a cycling incident, and has been ruled out of this weekend's Istanbul race.

Risatti won last year's Spanish Formula Three Championship and tested GP2 machinery before choosing to drive for GD Racing in the World Series.

"I'm very motivated and excited," said the 20-year-old from Argentina.

"This opportunity, which came by surprise, can with no doubt be a decisive turning point in my career. I'll have to do my best on an unknown track, but I'm sure I'll find a professional team that will allow me to concentrate on the driving part.

"I already tested a GP2 car during this winter, but I'll have to get used to it again, since my current ride is quite different."

Team boss Alessandro Alunni Bravi said he was disappointed for Maldonado, who won at Monaco earlier this season.

"Our first thought goes to Pastor Maldonado, who drove his car in an excellent way until now, handing us an incredible win at Monte Carlo, and showing our value and his abilities," he said.

"All team members feel sorry for his unfortunate incident, that's preventing him from racing at Istanbul. I'd like to wish him a prompt recovery, and all the team expect him back as soon as possible."

Bravi is confident that Risatti will prove to be a capable substitute.

"I'm glad I had the chance to sign him, since he did very well with Racing Engineering in the winter tests," he said.

"Anything came very naturally, as Ricardo and his father proved to be extremely fair and professional.

Their trust in Trident Racing is a further boost for the team; we'll work hard to give him a chance to score good results immediately."
