He was pathetic last night, no idea what some are saying in that he had a good game etc.
A striker leading the line needs to move...often and quickly...draw defenders out of position, make diagonal runs into & around the box and especially, behind the defenders. He does none of that consistently and some, rarely if ever.
Holding the ball up is also a must - not falling over at the slightest hint of a defender's shadow.
As for his first touch, it is simply not PL standard let alone European competition level.
The service has been poor and at times, players are clearly ignoring him but given how many times he nervously fluffs at the opportunities he has had, it is no wonder.
One thing I was sick of last night was his sulking. United have had too much of that from certain players and that simply cannot be tolerated. His arm waving and kicking posts whilst moaning at Garnacho and others was very poor from a teammate standpoint, regardless of how frustrated he was.
For me, he needs to go...just take the loss and sell him asap. United need a major upgrade at a couple of positions and striker is one of them. If he is not sold or loaned out, he is going to sit on the bench...just how good a teammate will he be then, when he isn't even playing?
