I genuinely think he is holding us back.
Its completely fine being slow, 36, often flat footed when watching others around you press more if you are clinical when the chances come your way. In my honest opinion he hasn't been clinical enough. Open goal versus City (he caressed the ball lethargically and it was an easy off-the-line clearance for the CB), one on one missed against Stoke in the first 2 mins and then yesterdays gaping header where he should at least hit the target. These are 3 examples from memory but I am sure there are one or two more.
I do wonder how our team would be different if we had Rashford in that central role, because whilst we miss out on the target man, we'd benefit on faster counters and more interlinking play with wingers. I wouldn't drop him just yet, but I do think he's starting to hold us back. Hopefully he can get that ruthlessness back. I don't think its a case of him being isolated because he is getting some very good chances.
