Former Man United captain Roy Keane said he expected Onana to return to the line-up for the second leg against Lyon on Thursday. "He is obviously under pressure, and of course, football is about making mistakes, but of course, if you're a goalkeeper and you make a mistake and it leads to a goal, then obviously, you're going to be criticised," Keane told Sky Sports. "It'll be interesting if he is left out today because I think it's also difficult for another goalkeeper to come in to get up to speed so quickly. Maybe he'll just leave him out for the weekend and almost recharge the batteries for the game coming up on Thursday, you know, we'll see. But that's the manager's job is to make big decisions."
