How old are you? Were you around for Rashford's debut?
Martial has been here for 6 years, he obviously has had some great performances up top. He also had a lot of shit ones, like the entirety of last season. It's not like apart from last season Martial was consistently good, more like hit and miss.
Rashford, Greenwood and James were all better out wide last season and even Amad and Elanga have looked better in their limited appearances. Mata was just as productive as Martial if you look at goals assists per minutes played (with Dan fecking James being twice as productive as both of them)
Stop living in the past. Last season Martial had one good game against City because he's big, strong and has a good touch. He looks like he can't be arsed for a very long time now.
