Sofyan Amrabat has been relegated to a part-time player after the emergence of Kobbie Mainoo.
The 27-year-old midfielder made an appearance against Manchester City on Sunday and gifted the hosts a goal.
And some Manchester United supporters are now blaming Erik ten Hag for bringing Amrabat to Old Trafford in the first place.
niima (all reactions via RedCafe): "A typical ETH choice, a below average player."
Born2Lose: "Can't fault Amrabat's effort, but he regularly plays suicidal passes deep in the Man United half. How a coach or Ten Hag hasn't picked him up on this is beyond me."
Gordon Godot: "This guy is who ETH wanted all summer by all accounts. Another ex-ten Hag player, anyone see a pattern here?"
lilcurt: "The straw that breaks the camels back on ETH this guy is. His signings have been truly awful on the whole."
E-mal: "I think ETH as manager doesn't appreciate how high level the EPL is when he continues to bring such average players to the club."
