Television footage shows that the Everton fan mocked Vieira when fans ran out on the field full time and Crystal Palace was defeated 3-2.
One could well see the Frenchman swearing before knocking out a fan who fell to the floor before Vieira was eventually taken away by other fans.

“I have nothing to say about it,” Vieira said in response to a question about the incident during his post-match pressure.
However, Everton manager Frank Lampard said he understands how difficult the situation would be for his colleague.
“I am worried about Patrick. I didn’t get it in the end. I would have said, “Come with us,” but he may not have wanted to. Of course, he ran 80 yards across the field, and it’s not easy.
“It was the pure admiration of the fans who came out on the field after escaping relegation. If done properly, let them stay on the field, let them have their moment. As long as they behave, no problem.

“We celebrate, they sing and greet, I turned right, and obviously the whole Sheffield Wednesday band came out on the field.
“I see a lady, she was lying on the floor where she was obviously just attacked. It’s all common knowledge, it went to police investigation and all at the end of the season.
