West Ham boss Alan Pardew has apologised to Arsene Wenger after the pair clashed on the touchline following the Hammers' 1-0 victory over Arsenal on Sunday.
Pardew and the Wenger squared up after Marlon Harewood scored a last-minute winner at Upton Park.
Wenger also refused to shake the hand of the Hammers chief after the final whistle.
"I apologise if I offended Arsene," said Pardew. "If I was over-zealous in my celebrations, which I'm sure I was, I apologise fully to Arsene and Arsenal.
"We've had a tough old season here and maybe it came out. Arsene was annoyed with that, maybe quite rightly so, but I hope that I can iron that out and we will be big enough to look each other in the eye.
"It was nothing personal, I was celebrating the goal. I've got great respect for him and that won't change.
"He is a top guy and I really respect him. I thought I was entitled to celebrate the goal after a pulsating game."
