At some point I do say Manchester united miss de gea, because onnana seem so unstable and irregular, he exhibit some level of unnecessary confidence which I think at some point is not needed and this has led to certain mistakes which cost the team the game, especially in this just concluded UCL game where he was not at his very best.
I understand where you are coming from, but the truth is that Manchester United do not miss David de gea; the keeper is past his best and it is understandable, buying a replacement with howlers does not negate the truth. With de gea, there will howlers in the fa cup finals, howlers in different competitions crucial stages.
At the moment, onana is getting exposed due to a poor tactical set up and horrible midfield; the coach needs to do better
