Only if we start acting as if his United career started from last season. The opinion on him (at least mine) is taking into consideration how things have gone in past many seasons. It has been a long story of seeing some form and then not seeing it for long then some form again. Every time, we think he is going to kick off from that and fulfil his potential, he goes down. After a point it is tiresome.
That's harsh.
15/16 - he was definitely good. Coming in as a 19yo and finishing the season as our top goalscorer, also winning the Golden Boy award.
16/17 - was disappointing. He had personal issues involving his family at the beginning of the season, was moved fulltime into a new position that he'd only started playing the previous season and was stripped of his shirt number (not exactly great for confidence), so it's understandable that he started the season poorly. He did start looking like himself towards the end of the season, but yeah we'll put this one down as a poor season.
17/18 - was our best left winger for the first half of the season and indeed was starting to be our best attacker again. Then we bought Sanchez and instantly moved Martial out of position to the right and then dropped him despite the fact Sanchez was performing nowhere near the level Martial had been.
18/19 - Started the season behind Sanchez again, but eventually Mourinho had no choice but to try something new and he put Martial back in on the left. Martial instantly went on a run of form that literally kept Mourinho in the job for an extra couple of months. Unfortunately in the second half of the season (after Ole took over) he was in and out of the team with injuries and illness.
19/20 - Moved back to striker, he was arguably our player of the season and finished as our top goalscorer again. Particularly at the end of the season he was the main player dragging us through the last month
So really, he's only had the one poor season. Both seasons he played as striker he was one of our best players, and in two of the three seasons that he played on the left he was one of our best players for the first half a season then didn't get to play much in the second half through no fault of his own.
Note that I'm not saying he's been super consistent. But in four of his five seasons he's actually been one of our most consistent players when he's been able to play. There's not much he can do when the manager refuses to do anything other than play Sanchez and Lukaku in the two positions he can play despite the fact Martial was playing better than them.
There's definitely a question over whether he can take the next step up, but he's done well enough that he's rightfully being given the opportunity to do so.
