Arsenal boss Arsene Wenger set for FA charge after shoving Anthony Taylor during Burnley win
But he made matters even worse by pushing Taylor as he edged down the tunnel and can now expect to be charged by the FA.
"I regret everything," said Arsene Wenger, who saw his 10 men go second thanks to Alexis Sanchez's penalty in the eighth minute of added time. "I should have shut up, gone in and go home. I apologise for that.
Referee Jon Moss looks set to include Wenger's antics in his post-match notes
"Look, it was nothing bad. I said something that you hear every day in football. Overall nine times out of 10 you are not sent to the stand for that.
"If I am I am and I should have shut up completely. I was quite calm the whole game, more than usual. But just in the last two to three minutes…"
Wenger declined to say what he had been so furious about, although the decision to play so much added time, with his men 1-0 up having had Granit Xhaka sent off in the 65th minute, is unlikely to have pleased him.

"What I am particularly upset about it's better I don't talk about that," he said.

Wenger added: "I didn't know if I was sent to the stands but I was sent out. I thought I could watch it from the tunnel. I went inside and watched it on television."

Wenger, though, did not complain about Xhaka's straight red for a wild challenge on Steven Defour. "He has to control his game and not punish the team with a lack of control in his tackling," said Wenger.

Express Sport brings you 10 key stats from Arsenal's win over Burnley
Burnley's penalty was given for a wild swipe by Francis Coquelin, which caught Ashley Barnes.
Clarets boss Sean Dyche was left scratching his head at another cruel late blow involving Laurent Koscielny. Ben Mee caught the defender in the head with a high kick to give away the penalty for Arsenal's winner.
Earlier in the season, Koscielny scored the only goal of the match at Turf Moor after a handball and this time was clearly offside in the build-up to the penalty.
"It's bizarre to think two last-minute incidents against the same side home and away have cost us two points," said Dyche. "Really you can't believe the decision. He is offside, two-thirds of a body's width.
"We can only hope over a season we'll get something back. If he had been level with him Ben would have dealt with him and the ball would have gone out."
