Only because he plays for Man U.
It's always funny when you lot overhype a player and the media jumps on it and backs you up. If you had Miley in your team, you lot would be calling him the second coming of Jesus.
We've seen him perform in the Champions League against top midfielders and even outperform Mainoo head to head, and we're not gassing him up as much as you guys are with Mainoo. He's standing out in your midfield because you don't have any ball carriers in it and that's what he is decent at.
Miley is over a year younger than him, has outperformed him, and isn't getting anywhere near the hype that Mainoo is. Mainoo would be nowhere near the England set-up if he wasn't at Man U.
Miley is actually in the top ten percentile for three of the main categories; he is close to the top ten in one more category and that is up against all midfielders. Mainoo is in the top ten percentile for one category and nowhere near in his next best category.
There is every chance he ends up another Rashford, on huge money, and never lives up to the hype.
