The "Mooy has been bad" thing is still going I see, despite absolutely no measurable evidence of him doing worse than he did before. Cant see him getting benched, he is together with Maupay our best and most consistent player. Trossard is far more likely to be in the danger zone despite his match winning capabilities.
Anyone with eyes can see Mooy's performances have dropped off recently. That's not to say he's bad, just that he's lost a bit of dynamism. Pre-January he was electric.
