On his day he's a wonderful player, but do we honestly think he is good enough to be the guy to build the team around for a top team?
A lot of noise from the manager and the club seems to suggest that he's a key player that partly determines how we will play going forward. I'm not sure his ability and production actually merits that. We treat him like prime Cristiano at times, and he just isn't anywhere near as good or as effective as he was. For one he isn't a very good central attacker, and doesn't have the ability to keep the ball effectively in tight spaces - which makes him less than useful as a central attacker. Like Cristiano he's not very effective tracking back, and needs other players to cover his defensive work and he's most effective in the attacking third where he is capable of causing havoc from the wing or with his movement in front of the defence. The problem is that all the thing's he does well, he does worse than Cristiano ever did, has less mental strength (who doesn't) and back then we had the team to support Cristiano's less than stellar defensive work - Rooney being key among them.
When Cristiano's defensive ability on the wing became a problem in big matches we went with a deep 4-3-3 with Rooney and Tevez out wide - two very hard working attackers who were excellent in tight spaces and allowed Ronaldo to focus on attacking. If we do this with Rashford he disappears, as he's neither skillful enough or strong enough to occupy that central attacker role. Plus, we don't have anyone anywhere near Tevez and Rooney's ability or work-rate in this squad.
I'm not saying bin Rashford - because he has a lot of qualities that make him a very good player to have, who can be top class on his day and will be a great option for any squad, but making him the player to build around seems very short sighted. He's not good enough for that.
