Yes Brighton team scored two goals it's really mysterious, although Manchester United team players were more aggressive than Brighton team. But only because of good luck, Brighton team managed to go, Manchester United players from all sides created pressure. Although the game ended up being a draw, it was really lucky to get success in extra minutes. And three points taken away earlier this season, but I never imagined Manchester United would perform so unconsciously. It is usually a last minute goal due to the inattention of the defenders and the goalkeeper.
Manchester United faced with more conceded goals and two ones are lucky for them. Their performance is made up of attacking, midfield and defense but their defensive performance in the match is bad. Their attacking system looks to be good but it is not enough to cover weakness in defense. Brighton can exploit Manchester United's defense very easily and if they are more luckily, more than two goals can be scored by Brighton.
A late winning goal from Brighton makes this match emotional for both with regret from Manchester United side but Brighton deserve this win. They shown their strength against a big team again.
Yea, this have been the major problem of Manchester united, and at first, I initially thought that they have have fixed it, but they have not, the problem I am talking about is their defense, they are too light at the back, and they concede too many chances, and sincerely speaking, any team that really want to compete in football in this 21 century must possess a good defense, but due to how porous Manchester united defense is, I don't see them winning anything tangible this season, unless their is a major improvement from them as the season goes by.
Lastly, I believe that the few new faces that arrived at Manchester united defense would have improved the team better than what I saw yesterday, but I was quite disappointed with their overall performance at the back, because they concede too many chances, and if Brighton was that clinical in front of goal, they would have scored more than two goals just as you rightfully said.
