In the Fulham loss the player I pitty most was Williams. The 34yrs old played the football with all his strength and might. He was practically seen running from post to post and he got some few important shots on target but David De Gea saved them.
Although his red card was deserving but Mitrovic acted so unprofessional and that was why he was booked.
Checking the severity of the offence of pushing ref, you don't dare a referee that gave a red card and still holding the red card in his hands.
Obviously Mitrovic is a professional. that game Fulham were clearly the better team until that incident. Before the red card Man United weren't that good. Yes, that's right, the way Fulham handled the situation was so unprofessional it was ridiculous. It was a clear penalty. There's no doubt. But the way Mitrovic and Coach Fulham reacted were ridiculous and exaggerated.
With this victory, Manchester United has the opportunity to get 3 trophies this season, Carabao Cup (already got), FA Cup and UEFA Europa League.
As you've stated, it won't be easy. Manchester City is currently playing better than Manchester United, and a final between the two will favor Manchester City. I'm not trying to downplay Manchester United because they've been doing well in the league as well, but it's clear that Manchester City is a step ahead of them. A final between them will be entertaining to watch, so I'm hoping for one soon.
I think all football fans really want the FA CUP Final to be the Manchester Derby, because obviously it will be a suitable final match and very interesting to look forward to. But I think if that final happens I'm sure Man City will win the match considering that Man City's game has been very dangerous lately, especially since Halaand's development so far continues to threaten every opponent.
