Lewis Hamilton was unmoved by Felipe Massa's comments about how the Singapore Grand Prix scandal cost him the 2008 drivers' title.
The Ferrari driver told Brazilian television that had the Singapore race not been fixed, he would have claimed the title he lost by one point.
"All of what happened was robbery – but regarding the race nothing has happened, the result remains the same. This is not right," Massa said in an interview with Globo television. "The robbery changed the outcome of a championship and I lost (the title)," added the Brazilian, out of action since his accident at the Hungarian Grand Prix.
Hamilton said on Friday in Japan that he was surprised by Massa's comments, but admitted he did not care much about the Brazilian's opinion.
"First, I have to say that it's good that he's recovering and back on his feet and back to his normal self and feeling good," Hamilton told reporters after Friday practice. "I think all I can say is that it was a tough season, things happened, there were lots and lots of 'what ifs' throughout the season, so I'm a bit surprised to hear him say that, to be honest.
"I believe we had a fair battle throughout the season, so I'm a bit surprised. It doesn't matter to me what he says, really."
Speaking about the Japanese Grand prix, the McLaren driver insisted he was thrilled to be driving at Suzuka for the first time.
"I love the track," he added. "For me it's the best track I've ever driven. Obviously it's different to places like Monaco but otherwise it's something very, very special for me.
"I had a great time today even though it was wet. We weren't supposed to be running in the second session, but I couldn't help it. I had to go out and have a little bit of fun."
