Newcastle ran out 2-0 winners in the relegation battle with Burnley.
Rafa Benitez’s side moved up to 13th in the table, overtaking Burnley and Crystal Palace in the process, and go seven points clear of the relegation zone.
But Newcastle fans were concerned about a potential flash point at the end of the game as Burnley defender Tarkowski trod on joselu.
Chris Sutton said: “I tell you what, Tarkowski here.
“I don’t know whether there’s a little stamp.
“I’m not so sure he catches Joselu here.
“He goes in, buys the foul and that’s… ooh.
“I don’t know if he catches him but the intent is there.”
Newcastle players also acted angrily at the incident as the game threatened to get nasty.
Mo Diame had already been tended to after getting caught by a Peter Crouch elbow.
Young midfielder Longstaff spoke about scoring in front of the home fans.
“It was a really good game, I knew it was going to be very tough but we took our chances in the first half and then the second half we kept their chances to a minimum.
“I say it everyday, I am in such a lucky position to be where I am, scoring and feeling the atmosphere tops it off.
“We know it is still very close and a couple of results can change it. We know we can change it by winning and it is a lot nicer to look up the table rather than down.
“I had about 10 people here, to have them here watching is a great night for me and the team.
“I can’t put the feeling into words just pure emotion. The atmosphere is amazing.”
