The two-week break since Canada has done little to ease Felipe Massa's anger following that clash with Sergio Perez.

Although he wasn't penalised for the incident - a move that many still find hard to believe - Massa remains angry at his Mexican rival for the incident that robbed him of a possible podium finish.

Having traded blows with the Force India driver via Twitter, Massa's mood was hardly lifted by today's news that the Stewards here are to take another look at the Montreal incident, a move which could see Perez' five-place grid penalty lifted.

"We saw that another driver had a lot of problems in the past and lost a race as a result of the accident he caused at Spa, but he learned," the Brazilian told reporters, clearly referring to another former 'bad boy' Romain Grosjean.

"This is something that he needs to learn," he continued, referring to Perez. "If I made a mistake I would be the first one to say 'it was my mistake and I'm sorry', like I always did when I made a mistake. People don't think in the same way, so I'm sorry for him and I hope he learns. Otherwise, he'll pay more penalties in the future.

"I will not trust him any more, definitely not," he added. That means if I am behind him again, I will think three times where I need to go because I will not know what he is going to do."

Told about Massa's comments, and asked whether he would be willing to sit down for a (groan) 'clear the air' meeting with the Williams driver, Perez said: "Yeah, of course. Felipe, we all know he is a good guy. He has his opinion, I have my opinion, and we just have to sit down. Also we get the opportunity tomorrow, with the FIA, to review the accident once again, as we believe we have enough evidence to prove I did nothing wrong."
