@JustinCase0110I don't think Antony will be useful at all. I'd love to be proven wrong, though.
I don't think he has the pace for the Premier League. He was found out very quickly, that he had only one useful leg, and that was so apparent especially in the match against Nottingham Forest. Esperito Santo had him fully worked out and his team completely nullified him. We only offered anything, really, down that side, after he went off and Diallo was sent on.
Pound for pound spent, he's amongst the worst signings that United have ever made. Not THE worst, but when weighed up against the amount he cost. The problem I see with him on the left is that you need pace to get past the full back, like Giggs had, and I don't see it.
One thing that puzzled me in the Forest game was a graphic put up by Sky at one point which showed over half of our attacks went down his side, 30% through the middle and only 18% down the left, where Garnacho was. If that was ten Hag's instructions, I don't understand them. It wasn't working; Garnacho must have felt unappreciated, and bored, and to not instruct them to attack down his side was simply incomprehensible.
