iSport International have announced Giedo van der Garde and Diego Nunes as their driver line-up for this year's GP2 main series.
The team had hoped to retain Bruno Senna, who they ran to the runner-up spot in the championship in 2008, if the Brazilian did not land a Formula One drive and had to return to GP2.
But Senna told iSport earlier this week that he would hold out for an F1 drive, and they have now confirmed another Brazilian, Diego Nunes, alongside van der Garde who is currently contesting the Asia series with the team.
"We are delighted to have Giedo and Diego on board for the 2009 series, " said iSport team boss Paul Jackson. "We have been building a good relationship with Giedo during the Asia Series and he was impressive during the winter testing.
"We were equally impressed with Diego after he tested with us at Paul Ricard last year, and with a year's experience in GP2 he will be a valuable addition to the team."
