Pardew apparently made a comment towards O’Neill when his team equalised late on against Sunderland on Sunday.
“I think I shall go and climb on the bus,” said O’Neill afterwards
“I wanted to have a glass of wine with Martin but I’m told he’s gone,” said Pardew. “Silly things got said on the bench, it got out of hand and it was unsavoury but it happens.
“It’s a passionate game but maybe I could have been a bit more grown-up about it. Maybe Sunderland’s bench handled it better. If one or two of us stepped over the line I’ll apologise for it.”
