Lotus could be set to announce its 2011 driver lineup on the verge of the Singapore Grand Prix in two weeks.
Finland's Turun Sanomat reported earlier from Monza that Heikki Kovalainen has penned a deal for next year, and that it is likely to be an extended stay with the new Malaysian-owned team.
The same source is now reporting that Jarno Trulli is also set to stay with Lotus, while the announcement of a switch from Cosworth to Renault engine power is also imminent.
Team boss Tony Fernandes, trackside at Monza this weekend, would not confirm the news other than to say he is happy with Grand Prix winners Kovalainen and Trulli.
Kovalainen has been linked with a return to his former team Renault, but Turun Sanomat said the Enstone based team is now likely to keep Vitaly Petrov next year.
