Tottenham managed to defeat Chelsea on Tuesday night in their Carabao Cup semi-final first leg at Wembley.
But it's fair to say it was under controversial circumstances.
Harry Kane scored from the penalty spot as Spurs won 1-0 on the night.
But there are many that feel that the penalty should not have been given in the first place.
Midway through the first half, Kane broke the offside trap and was taken down by Kepa Arrizabalaga.
Michael Oliver decided to consult with VAR to see if Kane was in an offside position but, despite it being extremely tight, it ruled that Kane was onside.
The English striker then buried his penalty and Chelsea could not reply.
Only one image was available of the incident at the time but another has now emerged following the final whistle.
And it makes for very interesting viewing.
Sky Sports showed Chelsea's analysis footage of the incident and the image suggests that Kane was actually in an offside position.
You can view the image below:
The image was shown to Maurizio Sarri who, after seeing the footage, then complained to the media that Kane was in fact offside.
"A few minutes ago I watched the video from our camera. It was offside. Our camera was in line with Harry Kane," Sarri told Sky Sports, per Goal.
"Offside with the head, the knee. Offside. It was really important the linesman carried on running, he had a big impact on our defenders.
"I don't think English referees are able to use the system.
"If you are not sure with the system, you have to follow the ball and at the end of the action decide.
"But he stopped it and didn't follow the ball - for our defenders it was offside. I don't know about the goalkeeper but sure the defenders.
"I think they have to study the system.
"It's very strange in the Premier League there isn't VAR and in Carabao Cup there is the system. It's very strange for us, the players and referees."
It seems he has every right to feel angry about the decision.
