If this was given as a goal against us I'd be mad, but wouldn't necessarily think there was a conspiracy against us, but more that referees are incompetent. And I can definitely see the side where Rashford is not interfering with play, at least by the law, so goal should stand. One takeaway from all this for me is that the rules need looking at, looks like every week we see one of this big calls in the premier league with the potential to massively influence the overall outcome of the league.
The referees are not incompetent if they produce a decision that fits the rules as they are.
I don't see why people, including Shearer, are clamouring that the rules need looking at.
The rules have evolved to where they are now as a result of previous remarks that they aren't clear enough and need to be more specific
Now they are carefully and precisely stated, arguably less ambiguity than in previous versions, but the complaints are coming from people who haven't read them, or haven't thought through them, or don't understand them, or haven't coached their players about them, or have coached the players but don't want to admit in public that the players made a mistake, or want some other new version instead, even if they haven't thought this through yet themselves.
None of that list of issues is the fault of the rulemakers.
This may lead to some reviews, but maybe it won't. It is allowed in plenty of other aspects of the game to play in a way that tries to trick the other team. It's surprising in the middle of all this that a famous striker Shearer is sticking up for socialising the risk of a goalkeeper Ederson having a dilemma about what he can see.
Whatever the rest of the argument, Akanji had the right to tackle or intercept, and the offside rule would in effect indemnify him against committing a foul, because the offside would then be called. If he didn't do this, either his decision was wrong or slow, or it might be down to not unfairness but the brilliance of the Casemiro pass.
