His fitness might be off a bit and he should be more a grafter in 50-50s, but I do think people are going overboard on the criticism regarding his attacking play and him being selfish.
He was very good that 1st half and there was a brilliant ball for Hojlund in that 1st half that he should have scored.
I think he does ever so well in several situations, but the decision making is overall crap.
But lets have a quick look at the video:
00:08: Bruno plays the ball back to Rashford who lost it from a poor touch. Reguilon is running in behind with plenty of space, there's plenty of angles for a pass. Rashford attempts a dummy to go past no less than 3 Brighton players. Fails. One pass in behind to Reguilon can potentially set him up for an excellent goalscoring opportunity, while even if Rashford manages the unlikely and goes past the 3 Brighton players, all he has is a chance to shoot from around 20meters.
The next clip is a much better involvement and a very good passage of play where we first lose the ball but then regain it and create a goalscoring opportunity, but do you really think the cutback and shot, from that angle, is a better decision than trying to pick out Højlund? Højlund is well positioned when Rashford goes for the cut back, a well placed pass between Dunk and the goalkeeper and a simply touch by Dunk could be an own goal, while behind him you have Højlund waiting for a tap in. I would understand shooting from the cut back angle when he has it on his right if that was instantly, but he has a great option to pass the ball.
1:07: Rashford does brilliantly to turn in midfield, but after this it's a disaster on display. He has Reguilon out to his left and in the middle you have Bruno not being covered at all and with miles of space to run towards goal. The only player that can attempt to go after Bruno is Dunk, but then he has to leave Højlund with space in behind. Rashford just continues his run more or less into Reguilon, who has to stop, then Rashford slows down to the point where there's no space for anyone to run into and he tries to go back two Brighton players and ends up with a throw in.
1:20: Brilliant cross for Højlund, but it's hardly a scenario where he should have scored. The timing of the run to get that burst to go past Dunk is excellent, and it's fine margins that he doesn't get a proper foot on the cross. This bit shows exactly what we need to take advantage of.
1:50 is one attempt too many at going past players, even though he succeeds. As soon as he receives the ball he has Casemiro making a run towards him, Rashford turns towards Brighton and loses the option to pass to Casemiro and he then has to evade two Brighton players. Ideally, just slot the ball in Casemiros path so that he can continue his run forward. It shows great ability, but it's also a numbers game and more often than not you won't get away with turning like that and maintaining possession. But this clip pretty much shows what people want from him otherwise. Reguilon makes a run in behind, Rashford picks him out and drifts into a position where he can get the ball back and shoot from. It's about taking advantage of the movement of your teammates and then getting into a better position to score from. Would've been a brilliant goal had we scored.
2:08 is a great pass to Højlund who has a shit first touch, it happens.
2:36: Has Reguilon out wide, tries to go past two Brighton players to line up a shot from 18meters. Fails.
2;58; Has Reguilon on an overlap and players making run in behinds, goes for a shot that gets deflected onto the post, again the wrong decision making.
3:48: Has McTominay making a run in behind with plenty of space, if McTominay gets the ball it would put him in a agreat position to shoot from and force Dunk to leave Højlund to attempt to block the path for McTominay. Rashford has no less than 3 Brighton players covering him, McTominay continues his run and Rashford tries to skip past 3 Brighton players, manages to pass the ball after the ball has rolled over the line.
4:20: don't mind that he shoots, the pass to McTominay is never really on, just poor execution.
4:46: Another case of holding on to the ball for too long and then attempting a pass.
5:10: Absolute disaster that he doesn't pass the ball towards the back post where Højlund is signalling he wants the pass. Brighton score their 2nd goal shortly after this situation
7:01: Does what he should be doing all match long when he has someone making a run in behind with plenty of spaces, passes it.
As a highlight reel displaying individual technical ability, by all means...But for me, and maybe it's just me, i find it bizarre that someone can look at that video, of a 25 year old Marcus Rashford (soon to be 26), and think it's a very good performance. The video mostly consists of poor decision making where Rashford is going for individual glory rather than the best options available. Player making an overlap, has space in behind, easy pass or attempt to go past 2-3 Brighton players for, best case, a shot attempt from 20meters.
