All that stuff might have been true upto 2019. He was delivering decent or very good numbers but was being shifted from left to centre to right to the bench. Given a run as undisputed #9, and he crossed 20 goals in an injury hit season. The stage is set, and...
That's when his form fell off a cliff. Not when he was undervalued, publicly criticized, rotated, dropped... He still has decent numbers and performances in the jose seasons. What happened from late 2020 onwards is different, and it's almost entirely on him. His dribbling, finishing, and even sharpness of passing all fell badly, which hadn't happened while he was struggling for his place and position.
I'm a massive fan of pre-2020 martial. I think his flaws are overstated, and his performances were pretty consistently good except for some variations of being a young player, different managers, positions. His finishing numbers were excellent and he was a slick passer and had awesome control. But his drop off since then is such a massive question mark over him, it's inexplicable, and makes it hard to believe the real player will ever be back for good.
