Expected this thread after the Forest game. First game in a while were he was better than decent and a thread asking why fans are concerned because apparently OP has a crystal ball and can tell that he will come good if we all just support him and ignore subpar performances because he's young, new and learning.
I'll speak for myself, but my concerns are as follows:
1. For the price we paid, we should be getting a player who causes the opposition enough troubles that they make accomodations for him freeing up the left wing where a Rashford ab hurt them. We see it with Saka and Martinelli every week. Martinelli is not as strong 1v1 as Saka, but as teams shift their defense naturally to the left to accommodate Saka (and Odegaard), they inevitably leave spaces for the likes of Xhaka and Martinelli to hurt them down their right - We saw this happen first hand in Sunday.
2. When a wide forward handles the ball, you see certain ingredients that tell you how good/comfortable they are, especially when facing the defender. One of those is control of the football, whether running with it or from a standing start. With Anthony, you can see he doesn't move well with the football, which ultimately makes him check back everytime he has it, allowing teams to get in shape.
Classic case of this we saw again on Wednesday, where after he beat that fullback, he shifted it back to his left because he knew he didn't have the pace to take advantage of the headstart he had.
Imagine a 22 year old Dembele, Saka, MG, Hazard turning around there?
3. Compared to other top wingers, he lacks any ball carrying ability. I have watched enough football and seen wingers travel with the ball over short and long distances, and I have never seen a player use Antony's technique of rolling the ball under his foot. For one, the ball isn't moving that fast. Two, it limits his own option as he cannot catch the defender out by changing direction. Three, again, it allows teams get in shape as most players are covering up spaces quickly - we saw this with Partey on Sunday.
4. His under/overhit passes.
Lastly, being concerned and discussing it is not the same as wanting him to fail or whatever nonsense some of you come up with. I never want any united player to fail. Some of us just do not have rose-tinted glasses for player or manager performance.
