Exactly. He should have ended the game after the equalizer - or at least before United´s corner. Then he panicked and "ended" the game too soon (when the ball was still in the penalty box) - without seeing a clear penalty in the process.
In any case, one of the most unfair results I´ve seen in a long time.
Brighton hit the woodwork 5 times
Denied 2 penalties
Man Utd first goal wasn't even a free kick and it was a foul on Dunk anyway
Matic should have been sent off
Game was allowed to carry on until the 97th minute after 5 minutes were given.
Unfair is putting it lightly.
