I don't know if you wumming or just plain stubborn. Regardless, as I said, look at the heatmaps.
This is Fred's:
And this is McT's:
I don't know about you but it seems pretty obvious to me that they spend the majority of their time more or less on the same line. Also, for anyone who watched the game, it was clear that McT was tasked to mark Grealish.
Well, I'll be damned....what do you know? That spot where McT spent a lot of time? That's exactly where Grealish spent the majority of his time too....
Now, that may be a coincidence or we may be sentient beings and admit that McT was playing in a midfield two with Fred and was personally marking Grealish.
