It's not entirely bullshit, because Martial has had patchy form where he's either very good or pretty anonymous and mediocre. His natural talent is one thing, but the consistency on the pitch is another.
No one is expecting him to be world class. He's just in a position for a giant club where inconsistency is rarely forgiven. He's a very good talent but that doesn't mean he hasn't had patches of poor displays that we just ignore.
The reasoning is that he has had mediocre performances that compliment the very good ones. His inconsistency is still a big downfall of his game, and he's running out of excuses at 24. Clearly, not according to
@Yagami below who thinks its down to lack of service (guess we have to add that to "he's on the LW it's not his position", "Jose played him wrong", "He was injured" and "he needs Rashford" to the ever growing list of excuses when he's playing poorly.
I named 5-6 strikers in my post, 2-3 from teams below us, 1 fighting relegation as strikers capable of more consistent displays than him this season. And you chose to isolate Augero? Also no one said Martial is shite. For what it's worth
I don't think he's .just mediocre either but I'm not going to say an opinion is incorrect about him being mediocre for us, when he has actually had quite a few mediocre displays. Talent is one thing, what you do week on week on the pitch is another.
