"I am just delighted for Paul Kitson," he says, "but I would have been more so if we had got three points instead of the one.
"Paul has been regularly scoring goals in the reserves and I am really glad for him, but I am just waiting for my chance because I haven't started in the Premiership yet."
It was a case of practice makes perfect for Jermain, whose volley looked to have been the winner until Charlton's injury time equaliser, and he reveals: "I have been practising the volleys in training a lot recently so it paid off.
"I thought we had won the game because there was not long left after my goal. I was so disappointed to see them equalise - it was unbelievable."
His composure in scoring the fourth West Ham goal was all the more impressive because of the haranguing he was getting from the home fans, but he says: "The stick didn't bother me and I get on well with the Charlton lads; I stayed out at half-time warming up and I knew what to expect, to be honest, but it didn't affect me and I got the goal.
"Eight goals in a game is really good for the supporters and now all the lads are looking forward to Tottenham on Saturday, hopefully we can get a few and win the game."
He admits, though, that observing much of the match from the bench alongside the coaching staff was something of an uncomfortable experience, and he adds: "They were going a little bit mad but, personally, I was just itching to get on. I was delighted when I did get on the pitch, and the goal was a bonus - hopefully I can get a few more."
However, after his second away goal in successive games, Jermain insists that he will not be demanding to start a game.
He explains: "I don't think I need to knock on Glenn's door; at the end of the day if I keep on performing and scoring then I don't think I need to speak to him - I will let my football do the talking and that is it."
