You see, I agree completely with your points about how they have been willing to track back. And how he shouldn't pander to youth. And that Martial's attitude has been bad.
And you're right, I shouldn't use the phrase of agenda, I regret that, as I don't like that, nor "fanboy" nor "hater" as terms which are used.
But what made me feel like you had an agenda is that you said he's done "literally nothing". That's simply not true. At the very worst you could say he's been as bad as the others. But he has done some good, and even great stuff, at times. As few and far between as they've been. Have the others really been better though? Worked harder, maybe.
Out of interest, where did you get your stats? I used who scored.
Martial: League 994, 3 + 4. Europa: 394, 1. Involved in a goal every 173.5 minutes.
Lingard: League 1002, 1 + 2. Europa: 274, 2 + 1. Involved in a goal every 212.6 minutes.
