He actually called him a cheating shithouse.

Maguire is right to call it out, he moves his leg out then stops part way. Havertz blantant cheating. Arsenal and the FA should discipline him, the FA certainly should have a word with the ref who lost the plot and got big calls wrong which contributed to him losing control. Needs to be way more accountability from refs. I know they are under pressure. if they can’t handle it then they’re not up to the job. Simulation and holding on at set piece has to be a priority to stamp out of the game.
