Luckily Manchester United did not lose in that match, but what is quite regrettable is how the second goal was scored by Lyon in the added time so that Manchester United failed to maintain the victory.
Maybe the coach is doing some experiment to understand why many good players and even goalkeepers play well in other teams but when they arrive at Manchester United they play worse, but strangely when they leave Manchester United they play well again.
