Felipe Massa appears to have narrowed down his post-Formula 1 options for 2017 to either a race seat in Formula E or the German touring car series DTM.
Earlier, the retiring Williams driver had indicated that Le Mans was another option.
"Things are going the way I imagined and I'm happy with my decision," UOL quotes Massa, who after 15 years in F1 will stop after next month's Abu Dhabi finale, as saying.
"I do not want to talk much about it, but it's all going the way I wanted.
"It's the most relaxed time of my career and I'm in no hurry [to decide what to do next]."
The report says that the former Ferrari driver is in talks with 'several' Formula E teams and is also interested in DTM, while WEC is less attractive because of the lack of competitive seats.
"The type of racing is the most important," Massa said. "DTM certainly has good races, and it's more competitive than WEC and Formula E.
"I'm in a position to choose where I'll have more fun and of course it's important to have a cheque to pay my bills."
Massa has won 11 grands prix during his F1 career.
