Rubens Barrichello is set to decide next week whether he will switch from formula one to the Indycar series for 2012.

F1's longest-serving veteran has been left without a race seat this season, but he recently enjoyed an Indy test with the KV team, in which his close friend Tony Kanaan is involved.

"There is a lot going on, we have spoken with many people and there are things to be resolved, including the family aspect," the 39-year-old told radio Bandeirantes on Tuesday.

"There is great anticipation and if everything goes well I think we can make the announcement of the decision early next week," added Barrichello.

I'm sure anyone who knows me can see in my eyes what I want. Rubens Barrichello

"I'm sure anyone who knows me can see in my eyes what I want. The first race is March 25 and there is no time to waste.

"If we want to be in a competitive way, everything has to be right and that means sponsorship, team, family -- everything."

Barrichello's first F1 team boss, however - Eddie Jordan - has urged the likeable Brazilian to forego the Indycar opportunity.

"I love Rubens -- our story began when he was only 19," the Irishman is quoted by Globo.

"I love his family, his parents, and I think he should retire with dignity."

Barrichello's contemporary David Coulthard, however, said: "I wish him luck in the United States. We had a great relationship throughout my career and I know how passionate he is about racing."

But fellow Brazilian Emerson Fittipaldi warned of the dangers of American oval racing.

"Today, Indy is different to when I drove -- the risk is higher but it is a risk that he knows he will need to take.

"Still, I think he can have fun doing what he likes," said the former series, F1 and Indy 500 winner.
