Kimi feeling heat: Masa

KIMI RAIKKONEN is feeling the heat at Ferrari despite his icy reputation and needs to chill out, according to the Finn's former teammate Felipe Massa.

Raikkonen has 'Iceman' tattooed on his arm but faces a storm of speculation about his future at Formula One's most glamorous team.

"Everybody says 'Iceman', I tell you he's not really like that," said Brazilian Massa, who partnered Raikkonen at Ferrari from 2007 to 2009 and was replaced by him in 2014.

"For sure he can suffer as well with the pressure and he shows that as well in some results," continued the Williams driver.

"He just needs to relax and try to do his best because he's definitely a big talent and can do a lot better than what he's doing. Everybody knows that."

Raikkonen, the 2007 world champion, is out of contract at the end of the season although Ferrari have an option on him.
