The fact there is a constant debate about Anthony Martial is significant. In my opinion, I don't see all this greatness that some feel he 'potentially' has. He isn't great around the box. Make some comparisons to similar players ok... Mane, Salah, Leroy Sane... Sterling (who has added to his game by scoring scrappy, critical goals and improving his effectiveness..) Ali, Hazard... and er, Sanchez.. attacking forwards who are clearly more effective and more of a threat than Martial. CONSISTENTLY.
Martial needs to improve and I get the feeling he has ended up believing his own hype. Opening up his body and firing right-foot shots into the net will only ever get him so far. He is one-dimensional and over-rated. All this talk about being the best finisher at the club is more of a testimony to where we are as an attacking side.
Martial is a good Champions League player, who can score the odd good goal. But, on his current form, he is no potential Man Utd star. If he is what Man Utd consider top-talent, then we aren't winning a thing. He wouldn't add or improve Chelsea, Liverpool, Tottenham, or Man City because he isn't better than the players there.
So why is he good enough for us? No left foot. You hardly see him head the damn thing. ALWAYS cuts inside and complicates the game, and narrows the pitch. He doesn't do the extraordinary. He slows the game down, and he isn't good enough to dictate games. Limited work-rate (just compare to Rashford) Sorry, I see a decent player, who is still working out who is as a player. and he isn't some new player / arrival at United.
I would take Sanchez in exchange for Martial and a few million in a heartbeat.
But I think I am in the minority on here with these opinions, and this is fair enough.
