He lost the ball under pressure in the first couple of minutes and pretty much treated it like a hand grenade thereafter.
We're trying to get our midfielders to collect the ball from the defence, back to goal and under pressure, then spin their man and launch an attacking move. It works with McGinn's arse, Kamara's nous, and Tielemans' control.
It doesn't work with Onana, that's just not his game.
