Sunderland manager Gus Poyet has shrugged off his touchline spat with Hull City boss Steve Bruce in Tuesday evening's 1-1 draw at the KC Stadium, claiming that "things happen" in football.
Poyet offered to shake the hand of the opposition manager, who refused the gesture - the Black Cats boss then clapped, with the linesman having to hold Bruce back afterwards.
Poyet told BBC Sport after the game: "In football things happen. I have to convince the officials not to put any buckets of drinks around me. I have no regrets whatsoever.
"If that is a bad image for football I am sorry but I don't think it's something to worry about. I'm old fashioned. What happens on the pitch stays on the pitch."
Sunderland remain 16th in the Premier League table.
