Leeds boss Dennis Wise has hit out at Luton counterpart Kevin Blackwell for being a sore loser.
The pair clashed at the full-time whistle while another former Leeds man John Carver also joined the fracas.
Wise believes the pair were simply 'bitter' at missing out on the chance to get one over their former club.
"I went over to shake Blackwell's hand and he seemed reluctant to," explained Wise.
"So I asked him if he had a problem with me and he told me to eff off, which wasn't very nice.
"I don't know what his problem is. He leant with his head in and made contact with the top of my head.
"John Carver came over and butted in and said something about a phone call. I have no idea what he was on about.
"They were obviously upset at losing what was probably the biggest match of their lives.
"Some people are just bitter. I can't help them with their bitterness."
