The two teams had traded hostilities throughout the contest and the clashes continued beyond the full-time whistle, with Arsenal midfielder Jorginho declining to shake the hand of his Newcastle counterpart.
And Lascelles said that the snub only made the win even sweeter, describing the Italy international’s actions as “not acceptable”.
“I’m just so glad that we beat them,” Lascelles said to the Daily Mirror. “Their captain Jorginho didn’t want to shake my hand after the game.
“I was fuming, it’s not on. I would never refuse to shake an opposition captain’s hand, no way. You can have as many arguments as you want on the pitch but shake hands at the end, it’s part of the sport.
”For me, whatever happens on the pitch - handbags or whatever - you show sportsmanship and shake hands afterwards. He didn’t do that, so I’m so glad we beat them. Players like that, I don’t think it’s acceptable.
“A lot of them walked in but I went up to him to shake his hand but he didn’t want to - and he’s their captain! There was a lot of that in the game but that’s football and we managed it well and kept our cool.”
Arsenal were furious that Gordon’s goal was allowed to stand after a long VAR check.
They felt that the ball had gone out of play in the build-up and Gabriel was pushed in the back before the Newcastle forward scored, while a tight offside decision was also cleared.
