I have learned a lot, says Bernoldi.

F1 rookie Enrique Bernoldi has revealed that he has a 'professional relationship' with his Arrows team-mate Jos Verstappen.

The comments are in stark contrast to those made by Verstappen who recently said the Brazilian was the worst team-mate he has ever had in F1.

Bernoldi said: "I have looked forward to being here because I have seen Indianapolis on TV. This is my first year, and I have learned a lot. Like being here, tomorrow will be the first time that I will get on the track, and tomorrow will be for just learning the track. I have won in everything that I have done, and learning to lose is harder than learning to win."

"We don't have the power, and early on the car was not competitive, but I'm learning and I think we are getting better. My teammate has been here, and there are times this year where I have been quicker than him. We will work together, but our driving styles are different. We have a professional relationship."
