McT might not play well but he does score goals. No way anyone would pick Amad over McT because Amad could maybe do well when McT is scoring important goals. I dont even like to see McT as a player for Manchester United but i wouldnt take the risk and take him off for Amad.
It isnt like ETH is afraid to give young players a chance. Mainoo and Garnacho have gotten chances and are basically starters now. Kambwala to a lesser extend got a chance. You want Amad to get a fair chance, are you willing to lose points to do that? ETH is under pressure already so he puts in Antony who, even when he is kinda shit going forward, but will keep the ball in the team and will work hard and help defending over a maybe situation with Amad.
This isnt a SAF Manchester United team where a young player can come in and play his game while Rooney, Ronaldo, Rio, Scholes, Keane or any of the other world class players do the hard work. This team needs every player to help the team win a game. This team doesnt even have a Virgil van Dijk who is so good that his CB partner is able to focus on his own game and play well.
And i do want Amad to be given a chance but currently isnt the time for it. It should have been during the first part of the season in easier league cup games or easier CL matches (with those opponents those should really have been there) but not now when every point counts. Unfortunatly Amad seems to have a knack for picking up an injury at the start of a season.
