Paul Scholes issues a withering verdict on ‘weak’ Manchester United keeper Andre Onana

United boss Erik ten Hag admitted his side are conceding too many goals but refused to blame Onana despite the goalkeeper’s errors at Galatasaray severely damaging their chances of Champions League progression.

Having lost three of four Group A games, Wednesday’s key clash in Istanbul began in dream fashion as Alejandro Garnacho’s early effort was followed up by a Bruno Fernandes rocket.

Hakim Ziyech pulled one back from a free-kick that Onana will be disappointed to have been beaten by and he was guilty of an even worse error after Scott McTominay scored United’s third.

The summer signing somehow failed to deal with another Ziyech free-kick and substitute Kerem Akturkoglu soon lasered past him as a mad match ended 3-3.

The result leaves United bottom of their pool heading into the final round of fixtures, with the concession of 14 goals in just five Group A games the key issue.

“We scored also quickly after each other,” United manager Ten Hag said.

“It’s about the point when you are leading, when you are 2-0 up and you have to manage the game. Not so easy.

“We give free-kicks away and we have to defend them better twice. I have to say also that is Hakim. He is brilliant, I know that. He is extraordinary.

“To give free-kicks, it’s difficult to defend as well. In such areas, we have to be in more control.

“It is always about incidents, always about details and some incidents we can manage better.

“As a team, we have to learn from it because we are conceding too many goals and it is unnecessary and avoidable.

“I am sure our team is experienced enough and capable enough to manage this and we will do better.”

Scholes was less forgiving on Onana, as he suggested the keeper was costing United time and again.

"What can you say? It’s a terrible mistake again (for the second goal). I’m sure if he is trying to punch it away with his right hand, it’s weak,” Scholes told TNT Sports.

“He makes people nervous. I think he makes his defence nervy, his team nervous. He makes simple saves look really, really difficult.

“You see him again here at the near post (for the third goal). I’m not a goalkeeping expert and others will know more about this, but I don’t think he should be beaten at the near post. His positioning is poor. For me all three goals are down to him.

“In the last few weeks in the Premier League he has started to look okay, he’s looking a lot better. He makes unconventional saves, but it is the Champions League that has been a real struggle for him.

“I don’t know why, has he been too casual? I just think he’s a bit relaxed, his concentration isn’t all there. For a goalkeeper, concentration is the most important thing…

“You think of the other team and you’re looking at a goalkeeper and he’s nervous, you think ‘I’m just going to shoot and get the ball around him’. He looks like he is going to concede every time.”
