The former world champion Jenson Button expects Ron Dennis to restore McLaren to its former glory after returning to take overall charge of the Formula One team.
Dennis is back in his former role as McLaren's chief executive officer after ousting Martin Whitmarsh in a shareholders' vote.
The 66-year-old has been given a mandate to conduct a thorough review of McLaren's operations and the first major change will be the replacement of team principal Whitmarsh, who has suffered five unsuccessful years in charge.
Eric Boullier is widely tipped to take the post after resigning from his team principal role at Lotus on Friday.
Lotus named co-chairman Gerard Lopez as Boullier's replacement.
The Dennis revolution has already triggered a surge of enthusiasm at McLaren headquarters, with both star driver Button and managing director Jonathan Neale showing support for the changes during the launch of their MP4-29 car.
