Agreed. Besides speed there is little Rashford has in common with Coley.
Perhaps if Rashford bulks up he can be the back to goal player Cole was. His game would have to change markedly though.
Rashford is more like Henry, stylistically. Plays on the half turn, prefers to have the ball in the channel so he can square up defenders.
The kid has to become more lethal in front of goal. Yes, it's hard. That's Man Utd though. At the biggest club in Britain there is always gonna be pressure. Rooney learned to cope with it, so did Ronaldo. If Rashford is gonna be the player we all hope he will, Rashford will learn too.
A different pressure comes with being the best player for a team that finishes seventh or fifth. For example, Januzaj and Martial. And a team that, genuinely, wants to get back to trying for serious trophies.
People will say it's unfair to expect Rashford to have a Michael Owen style growth curve. If he's as good as we think he is, as good as United's aspirations demand he becomes, Rashford will get stronger under the weight of expectation not crumble.
