The thing is though, Martial is not a winger or left midfielder like Young. He played last season and at Monaco as a left forward, which is basically as a striker that drifts/cuts in from the left. He didn't previously have the responsibility to provide so much width or track back as deep as he is expected to do now. So to compare him with Young in that regard, is to me a bit like comparing Mkhi with Fellaini, apples and oranges bar some generic footballer attributes. I agree with
@kouroux in what he expects from his players, I see the same as him, but I'm just not sure it's the right approach to this with regards to Martial.
I'm not gonna compare Martial to Hazard and C.Ronaldo with regards to their quality (obvious gulf there) but in the way these players, who play basically the same position, have been managed by Mourinho.
- Ronaldo was unwillingly absolved of any winger responsibilities (tracking back, providing width) and basically given the freedom to do as he likes. Partly because of his phenomenal output, partly because he told Mou to simply do one when asked to do so (perks of being a mega star) who knows. It arguably worked for Ronaldo and RM even though his relationship with Mourinho was beyond frosty because Ronaldo wouldn't follow instructions regarding tracking back. Mourinho eventually gets axed.
- Mourinho leaves RM, goes to Chelsea and tries to do with Hazard the same thing he wanted Ronaldo to do. He's trying to turn him into Willian, to track back and to be positionally disciplined. Eventually it backfires, Hazard downs tools and doesn't see eye-to-eye with Mourinho and I think we all know how that ended up.
- Jose then comes to United, finds Martial who under the freedom given to him by LVG had a POTY season with 17 goals and again tries to turn him into a hardworking winger same as he tried to do with Hazard and Ronaldo before. Result is Martial either gets axed (earlier in the season) or is out of the team and playing with no confidence when he comes on. The team loses an attacking threat which it badly needs and struggles to find from elsewhere.
He does have this obsession with players in wide forward positions working very hard for the team and being very disciplined. His track record of success probably validates him, but he did basically fall out with his star players for that very reason. Personally I would prefer a 17 goal a year Martial than a Young type of grafter
any day of the week. The team does not have a problem with shipping goals anyway, it has a problem with scoring them. You can find Young type players (grafters with limited technical ability) for a dime a dozen, but you can't find 17 goal-a-season wide forwards easily. Letting him be tactically and defensively ill-disciplined would not kill us, if he managed to produce a goal return that warrants it.
Again, I'm not absolving Martial of blame. He has underperformed and he does need to do better. My problem is that Mourinho's approach of favouring his grafters has not really helped him so far at United. We are 5th on the league table. He loves his Fellainis and his Youngs and it occasionally works for us, but it's obvious to me that we're not gonna win titles with these players in the starting XI. I'd happily eat my words if he proves me wrong, by the way. But I'd like him to work with and get the best out of his genuinely talented players (Mkhi, Martial, Mata, Rashford) instead of just ostracising them from the squad because they don't work hard enough in defending.
