Speaking to Brazil's Globo, the former F1 driver said: "We can never say never, Michael Schumacher and Kimi Räikkönen returned. In life, I think we have to have the dream of wanting to improve every day. When the door is there, I can not say no."
Barrichello, who scored 658 points, picked up 11 victories, stood on the podium a further 57 times and claimed 14 pole positions during his 19 year spell in F1, went on to talk specifically about the comebacks made by his former Ferrari colleague Michael Schumacher and 2007 F1 World Champion Kimi Räikkönen, explaining that preparation is key to success.
"We have the example of Schumacher who returned and did not come prepared. I thought Räikkönen would have the same difficulty, but he had a sensational year. He is third in the championship, not directly fighting for wins but has scored six podiums. I say that because I have not stopped, I went into another category. I'm more active. In physical and mental conditions, I would be prepared," Barrichello added.
