Liverpool continued their unbeaten start to the Premier League season with an important 1-0 win over city rivals Everton.
Jurgen Klopp's side were frustrated throughout by Marco Silva's team, but snatched three points in the 96th minute under the most bizarre circumstances.
Jordan Pickford for some reason tipped Virgil van Dijk's mishit volley onto the top of the crossbar, with the ball then bouncing down into the path of Divock Origi to tap home.
It means Liverpool are still just two points behind Manchester City and the celebrations from Klopp summed up just how important Origi's strike was.
The German manager sprinted onto the pitch to celebrate with Alisson Becker. You can watch the footage below.
It's not something a manager should do, but in the heat of the moment, it can be forgiven.
However, one man who was not in a forgiving mood was Danny Mills, who launched a scathing attack on the Liverpool boss.
"I would like to think that Jurgen Klopp will get into trouble for that," Mills said, per BBC.
"If other managers do that - and we know one in particular - he'd get absolutely slaughtered.
"I think it's absolutely shocking what Jurgen Klopp does. Ok, go down the touchline a little bit, come out of your technical area, celebrate with your staff on the bench - I don't have a problem with that at all.
"But to run into the middle of the pitch, I think it's disrespectful to Everton.
"There are so many managers that get absolutely hammered but Klopp is very media friendly, everybody seems to love him and he can't do anything wrong.
"You cannot go on to the middle of the pitch, no matter what the circumstances."
As expected, fans were not happy with Mills' comments and made their feelings well known on Twitter.
John Arne Riise had his say, while even Jake Humphrey and Chris Sutton defended Klopp.
