But it was clear that the recent surge in stories suggesting Rubens might be eyeing up other options were starting to grate. "He's free to do what he wants but I'd like to get some clarity because I keep hearing all these stories about where he might be going," Vasser told SPEED TV.
"We're working on Rubens and EJ's deal is always year-to-year. The only thing I can tell you for sure right now is that we're 100 per cent committed to run Tony Kanaan next year."
While talk of a return to F1 seems somewhat far-fetched, it's the possibility of Barrichello moving to a rival IndyCar team that is really gaining momentum as the end of the current season draws near, and everyone starts thinking about their plans for next season. In particular, there are persistent rumours that Honda want Barrichello back in their fold, after their time together in F1 at BAR. That would mean Barrichello moving away from the Chevrolet-backed KV Racing team.
"We definitely want to run a second car [in 2013]," confirmed Rob Edwards, manager of Sam Schmidt's Honda-powered team. "Sam and I have a list of drivers we're interested in and we're going through it [but] you would have to ask Rubens if he's interested in our team."
Rahal Letterman Lanigan Racing - also running Honda engines and currently fielding a fellow F1 graduate in the form of Takuma Sato - is another team being linked with Barrichello for a prospective sophomore season. "Is Rubens a guy that we'd look at? Absolutely," confirmed team co-owner Bobby Rahal, also a former Champ Car driver and Indianapolis 500 champion. "He's a good driver, I like his personality and he could be a leader in the team."
But the most tantalising possibility of all is the fourth seat at Honda's flagship team Chip Ganassi Racing, which appears to be vacant following news that Graham Rahal is now a free agent
"I just met Rubens for the first time, briefly, last weekend at Mid-Ohio," said the team's managing director Mike Hull. "If he's available and we can put it together, it would be great for us." However, he emphasised that there had been no serious discussions about the prospect between the team and Barrichello.
Frustrations about his transitionary year aside, it still seems that Barrichello is enjoying his racing enough to ensure that he continues in competition again in 2013 if the right opportunity arises. Whether that's in F1, or at KV Racing, Ganassi or one of the other IndyCar teams coyly throwing glances in his direction very much remains to be seen.
