Lotus Renault team boss Eric Boullier has praised Kimi Raikkonen following his success in the Australian Grand Prix on Sunday.
The 2007 world champion's triumph made it two wins in his last four races, with Boullier insisting that the 33-year-old is back to his best.
"Kimi built up himself over the last year. You could see a strong second half of the season in 2012," Boullier told Autosport.
"And he is starting the season like he finished last year. We can expect him to be strong."
Raikkonen finished third in the 2012 season.
