We looked better upfront with him being deployed as a winger. He has the pace and the skill, and it's not a role that is foreign to him at all.
LVG probably put Rooney in front to handle the finishing, letting the young Martial do all the work. It's kind of funny when you realise that Martial is being over utilised, in order to support a man who performed a similar task for the team for almost a decade, which will inevitably have an effect on his end product, but make the team better,overall.
Hopefully, this doesn't become a permanent role, as it could lead to exhaustion and a decline in performances in his late 20s, and ultimately, and if history is anything to go by, his goal scoring is going to be heavily criticised in the "Is Martial a legend and where does he rank, if yes?" thread in 2025.
