That's really not true. Even though we've created loads of chances this season most of them haven't fallen to Rashford as he hasn't played up top. For a better comparison we should look at Rashfords conversion rate last season which was ridiculously good when he was actually playing up top.
It is true. Rashford himself, regardless of whatever position he has been listed on the team sheet, has wasted a large percentage of his opportunities this season, much larger than he did last season. Which is fine of course, but it is what happened.
People always do this. If not challenged early, it will just be accepted as fact that Rashford simply didn't score for months due to him not having goalscoring opportunities, so he can't be compared to Mbappé for example, who plays upfront for an attacking team.
Firstly, WE are an attacking team. On his conversion rate from what I've seen, Mbappé would have more goals than Rashford if he had played instead in THIS United team. He simply seems to take a higher portion of his chances, which has nothing to do with who he plays for. United have had games where hey have had over 30 shots on goal and not scored this season. How many do you think Monaco have per game? 90?
Our forwards, Rashford included, have been guilty of profligacy this season. I'm a fan, and am not attacking him for this, but I also won't deny it and imply that he has had an impressive chance conversion based on some imaginary circumstance of him getting no scoring opportunities due to being mismanaged. It is also baseless to say that he would emulate Mbappé had he been at Monaco instead, as Mbappé has his record due to taking more of his chances than Rashford does. Mbappé would have probably scored against Middlesborough away, for example, if he had all of Rashford's chances.
Both are top talents, it consistent finishing is certainly a weakness in Rashford's game that he needs to work on in order to reach the very top. I think he will, as he's technically brilliant.
