There have been a lot of controversy in the game against Chelsea vs Fulham. The Fulham supported are angry they were rubbed off a clear goal in the first half, and honestly the VAR would've stayed out of it, it was an accidental foul as the player was in possession of the ball. During the second half another foul happened on Jao Pedro before touching the hand of the Fulham defender but they were awarded a penalty. I think the VAR system needs to be rechecked, and apologies should later be giving to Fulham.
The VAR system is getting worse instead of controlling the game the right way, they are now making some wrong decisions that do cost a lot of teams to drop some vital points which is very wrong.
Now they decided to be announcing their decision which up me have no change with the previous rule because they will still the once to make the decision for the general public, no once can contradict them, and after the game, they do mostly come to apologize after realizing their mistake in making decisions.
Chelsea win the game, and even with the VAR intervention, they looks very solid to win the match even though Fulham was also very strong in the game.
I watched this game

Manchester United needs to improve a little, but in attack, in defense they are a big disaster, they managed to dominate the game, but the opponent was much more effective in attack because they managed to take advantage of the chances they had, thanks to the penalty Manchester United won, but if they do not improve, in the next games they could have consecutive defeats if they face strong teams
Manchester United have a very solid attack but the manager is not using them well to get the right win they deserve that is why the team is struggling to win matches. But I agree with you that they need to strengthen their defense because the Burnley attack was very good that was why Untied defenders struggled in the match, the management should consider signing some good defenders before the end of the transfer.
