Glenn Roeder insists he did not intend to incite the West Ham United fans upon his return to Upton Park.
The Newcastle United boss oversaw a 2-0 victory for his troops in the capital, with Damien Duff and Obafemi Martins on target.
But Roeder infuriated a section of the home faithful when he applauded the visiting fans, who were chanting his name.
Police had to restrain some disgruntled West Ham supporters and Roeder apologised for the furore his actions caused.
"I'd like to say if I've upset anyone at West Ham today, I want to apologise," Roeder told Sky Sports.
"I think people know Glenn Roeder in football well enough that I'm not an excitable person, but our fans were singing my name and I gave them a wave three or four times, which was quite unusual for me to do.
"I'm normally quite a calm character, but obviously it caused a problem amongst the West Ham supporters. I want to apologise for that.
"It was not intentional and it was not anything to do with me being back at the club and winning, it was a question of me acknowledging our fans.
"The last thing I wanted to do was cause a riot or anything like that. I must admit I became aware quite quickly that people were becoming upset and, thereafter, I didn't go to the touchline and do any more waves.
"I think my reputation is good enough when I say I apologise and didn't mean it, that's the truth."
As for the on-pitch events, Roeder praised the display of Martins after the Nigerian striker notched his first goal for Newcastle since his £10 million move from Internazionale.
He added: "It was very satisfying and I thought we played extremely well. There was no doubt we deserved the win and we should have been in front at half time with the couple of chances we had in the first half.
"It was a very professional job done by a team which is very motivated and very together.
"I wouldn't normally want to single anyone out, but there is one because he broke his duck today and got his first goal, and that was Obafemi Martins.
"He cost £10 million, he's come from Inter Milan, he's a young player who's 21 and not a player with great experience, although he's come from a great club.
"When you are 21 and come to a club like Newcastle, it's tough, and all the boys were willing him to get that goal.
"His finishing in training is sensational and you will see some great goals from him over the next few seasons. He is a serious finisher.
"He was getting a little uptight at not getting that goal, but he has showed a cool head with the way he slotted it in."
Newcastle suffered an injury scare towards the end of the game when Shay Given was stretchered off after a collision with Marlon Harewood, although Roeder expects his number one keeper to be fine in the long run.
Roeder continued: "I'm hoping it's nothing more serious than winding. He couldn't get his breath.
"He's back in the dressing room now and is just starting to breathe properly. It was a potentially nasty moment for Shay, but, fingers crossed, I think he is going to be okay."
