Arden sporting manager Julian Rouse has applauded Antonio Felix da Costa's attitude to racing for and against his team in Formula Renault 3.5 and GP3 this year.
Da Costa started the year driving for Carlin in GP3, before being drafted into Arden Caterham's FR3.5 line-up mid-season when he was picked up by Red Bull. He continued racing in GP3, where he was fighting against Arden's Mitch Evans for the championship.
Reflecting on the situation, Rouse believes the Portuguese racer handled things very well.
"The rivalry was good fun actually," Rouse said. "It created a good level of banter.
"It was a testament to Antonio's personality and his professionalism that he really embraced that, and he never allowed the two programs to cross over. I don't think there are many people that would have been able to deal with that situation and produce the results that he did [three wins in GP3 and four in FR3.5].
"He's unique. He has a high level of intelligence and an ability to motivate the people around him. That's a key factor."
