Their is a difference between stating this player(Martial) will be a good or even top player(Saha level in his prime or even Benzema level), to saying he is going to be a contender for Ballon or D'or(Suarez level). One is massively overrating his ability, while the other is being realistic which is me. And that realism has me questioning why we payed Suarez type money for him when he has yet to accomplish anything. Even though, I should not care how much we pay for a player as long as he comes good, I feel it is ethical to voice my opinion towards an overall strange transfer dealing.
If Van Gaal rated him so much, he would have been a priority signing alongside Depay, Schneiderlin, etc., rather than one that seems panicked because we were low in the attack. If we were more decisive, we could have gotten him early this transfer window and at a price that does not seem questionable towards our integrity. When United bought Ronaldo, he was not being labelled as a ballon D'or winner then and the expectation and price was reasonable. That is how a player should be bought and monitored. What we did with Martial is like buying Hernandez from his former team in Mexico for a crazy amount of money and saying he is guaranteed to be a world class player. This guy can't be the same with Ronaldo because he is expected to succeed and be a world class player no matter the cost. It is like the same pressure we are putting on an established player, we are putting on a teenage, which is poor management.
