Manchester United great Peter Schmeichel says Andre Onana was to blame their Champions League 3-3 draw at Galatasaray.
Schmeichel says United's goalkeeper was at fault for all three goals conceded.
"Do you know what? I think the back four played very well today, I don't think they could have done much more," he said on CBS Sports.
"Again though, you can't argue, the mistakes by the goalkeeper are very, very expensive.
"Every time a goalkeeper makes a mistake, it is a goal, that is just a fact of life. If you go back to Sunday, everything worked really well but when you play at this level, every little mistake you make is being penalised and you have got to learn that."
