Erik ten Hag says Manchester United are conceding too many goals ahead of Saturday night's showdown with Newcastle United at St James' Park. But he refused to blame Andre 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 Man 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 Manchester 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," 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. What is enjoyable is the progress we have and the way we play football. We dictated the game, we scored so many goals - it was about plan, creativity, being proactive and brave. That makes me happy."

Onana will be again under the spotlight in Saturday's game against Newcastle, having also been guilty of errors in the losses away to Bayern Munich and at home to Galatasaray. While his key stoppage-time penalty save secured a win against Copenhagen, he endured another difficult Champions League night on Wednesday.

"I think as a team we played very well," Ten Hag said when asked about Onana. "We win and lose together. You see the progress in this team. I take many positives from this game. Some mistakes. We played like I want my team to play.

"It was enjoyable to watch that proactive, dynamic, brave and we scored great goals. Even after we had some setbacks, we kept going until the end and we should have won with big chances from Scott McTominay and (Facundo) Pellistri.

"Of course, I am disappointed because we should have managed the game better, we will learn from that. Because this team is in development."

Asked how Onana is, he said: "He is OK. As I said, it is not about individuals. Of course, individual errors in football can make a difference and you take responsibility for it but it is always about the team.

"This team is good, all the players in the squad are good and deserve the best to play for Manchester United because they are brilliant players. And that counts for the whole squad."
