West Ham striker Craig Bellamy shrugged off a bust-up with Birmingham's Olivier Kapo during Saturday's victory.
"What happened with Kapo is just part of the game. I'm not going to blame anyone.
"They're showing passion, the same as I am. There's nothing wrong in that. In fact, it gives me more respect for them.
"As for the penalty, I don't even need to get into that.
"The decision was made correctly. Look at the replays and you'll see for yourself.
"The linesman was right there. If he had been on the other side it might not have been so clear-cut but he had a perfect view."
