Ah yes the good ol days. When genuinely contentious moments happened organically due to endless flowing football. When the ref saw what he saw and made a decision, and stuck with that decision. And sometimes there was outrage over his decision, and there was passion. And one set of fans felt that they were undone and the other set of fans felt that it was justified. What I would give to see football like this again, to see a call like this made and everyone having to live with it, and react to it. The best part about it was there was no waiting. It all happened in one moment and that was it.
As to the decision itself, well I can understand the viewpoint of the commentator, outraged by the decision. There's a lot to unpack on this tackle. First, the claim that Berg "clearly" got to the ball first. Well, lets go piece by piece. The through pass bounced through Berg's legs onto Sharpe, who possessed the ball and dribbled it forward back into direction of Berg who was closing down. So the ball was played forward by Sharpe, right into the path of Berg, who found the ball at his feet and kicked the ball through for a would-be corner kick right as Berg shoulder barges Sharpe and they both go down.
What did the referee see? He saw the shoulder barge, he saw Berg not playing the ball as much as he collided into Sharpe. Now, on the other hand, technically Berg did kick the ball right as they collided, but he didn't "clearly" get to the ball before they collided. From the replay, you can see that their upper bodies collided at about the exact moment as Berg kicked the ball. And it wasn't clear that Berg was actually even playing the ball. Yes he got to it, but only because Sharpe had dribbled it forward in his direction. If we're honest Berg couldn't avoid kicking that ball as it was directly into his path.
So the reason for the instinctive decision by the referee to call a penalty and send him off was due to the shoulder barge, the actual impact of his upper body into Sharpe was what he saw. The fact that Berg kicked the ball forward, technically getting to the ball right as that impact happened makes it a difficult call.
I personally think that the best decision there would have been to not call a penalty and allow it to go for a corner kick, given that they both were converging on each other and arguably brought each other down. And the fact that Berg did get his foot on to the ball right as that was happening, though he didn't get his foot onto the ball "clearly" before the impact nor was it clear that he was actually playing the ball. It could also be fairly and reasonably be interpreted as the referee did, that he simply found the ball at his feet and that his upper body smashed into Sharpe in a manner that brought him down.
Now imagine for a moment that this went to VAR review, what do you think would be the result? If I had to guess, I would bet that they would see the shoulder barge and uphold the referee decision of penalty, maybe they would reduce the red to a yellow, but they would probably still give the penalty due to the way Berg was coming in hard in the upper body, and seeing that although he got his foot onto the ball, it wasn't "clearly" before the shoulder impact, and he wasn't clearly making a play on the ball, but rather that he just found the ball at his feet from the dribble from Sharpe.
So for all the outrage there, VAR wouldn't necessarily have overruled the decision and made it a corner. I personally saw nothing wrong with the referee giving a penalty and sending him off, though I would say it was a bit harsh but I wouldn't call it a howler.
The referee saw the way that Berg rammed into Sharpe with his shoulder who was dribbling through the box and he lost his opportunity for a shot on goal. Berg could have slide tackled that ball forward not and not brought Sharpe down and it would have been a corner.
In conclusion, this was a contentious decision, a decision that you could reasonable argue should have been a no-call and a corner kick, but that kind of collision in the box (pre-VAR or with VAR) generally would always cause a foul to be a called, and since the attacker was dribbling into the box he had his goal scoring opportunity taken away from him.
While I personally would have preferred to see a no-call be given here, I have no issue with the referee's decision. Seeing a dribbling attacker entering the box and then being brought down, it's hard for a referee not to call that a penalty in real-time. Again, harsh but not unreasonable given how hard Berg went into Sharpe with his upper body who was merely trying to maintain his dribble forward into the box. Berg did get his foot on to the ball and kicked it forward right as that collision was happening, but not clearly "before" the collision as was argued by the geuninely emotional and passionate commentator, which was fun to see.
See the way that commentator reacted to that is what is missing in today's football. There's no longer genuine passion like that. That kind of passion and ballsy refereeing what is missing in the sport we all love. And I love seeing the players protest and the referee standing his ground and pointing to the spot.
