It's not about having a good game or not at this point. When it's not convenient for him, he's not going to help out his teammates. That's it. Last night, it was not convenient for him. He made zero attempt to help bring the ball out from the back and zero attempt to make himself available every time Arthur was being roaming around fending off pressure.
My assessment of him has always been that when he has time and space, his intelligence can shine through and he can make the cute little touches or nice long passes, but when the game is on, he's as good as playing with 10 men. He probably looks great in training when the intensity is lower than in games, which is why coaches rate him so much.
