da fezbet： The £47m 'keeper's litany of blunders threaten to cost United their place in the knockout stages – and leaves Erik ten Hag facing more tough questions

da bet nacional： It was no secret that Manchester United signed Andre Onana for his outstanding ability on the ball rather than his shot-stopping qualities. But their desire to improve their build-up play after 12 years with David de Gea meant that they overlooked the fact that the primary job of a goalkeeper is to stop the ball going in the net.

And based on the last four months, that is a task that seems to be beyond Onana. The Cameroonian's short career with United has been a traumatic experience for everyone involved, beginning with him getting lobbed from the halfway line on his Old Trafford debut in a friendly against Lens.

But Champions League nights have been particularly harrowing for the £47-million ($59m) signing, and his disaster-class in the 3-3 draw at Galatasaray, which leaves United bottom of Group A with one game to play, was the worst of the lot.

For United to reach the last 16, they now need to beat Bayern Munich in their final group game and hope that Galatasaray and Copenhagen's match ends in a draw. In other words, they need a miracle. And if they cannot pull it off, Onana will be the biggest culprit for their return to Europe's elite competition being short-lived.

Onana had a rough start to life in the Premier League, conceding 16 goals in his first 10 matches before keeping three clean sheets in a row. But his numbers in the Champions League have made for even grimmer reading. In just five European matches for United, the Cameroonian has kept just one clean sheet while conceding 14 goals.

That gives United the second-worst defensive record in the Champions League, only trailing Royal Antwerp, who have let in 15. The Belgian champions can be cut some slack as they are playing in the competition for the first time since 1957, but United, as three-times European Cup winners, have much higher standards. And Onana is simply not meeting them.

While United's outfield players may not have helped Onana out by failing to see games out and squandering the lead on three occasions, the goalkeeper has been the architect of their downfall more often than not. Onana has made standout errors in three games in particular, of which United ended up taking just one point out of a possible nine.

His traumatic campaign began with him letting Leroy Sane's tame shot squirm under his body to give Bayern Munich a 1-0 lead in their eventual 4-3 win in Bavaria. Against Galatasaray at Old Trafford, meanwhile, with the game tied at 2-2, he made a careless floor pass which was scooped up by Dries Mertens. His mistake forced Casemiro to make a last-ditch tackle, leading to him conceding a penalty and getting sent off. Mauro Icardi missed the target from the spot, but Galatasaray eventually made their numerical superiority count and the Argentine scored a few minutes later to clinch a 3-2 win.

Onana's terrible run against the Turkish giants continued in Istanbul, when he failed to organise his wall properly for Hakim Ziyech's first free-kick and got his positioning badly wrong to concede the goal which halved United's advantage. But that error paled in comparison to the gaffe he made in the second half from another Ziyech free-kick.

This time Onana didn't even bother to assemble a wall, which invited the Morocco international to shoot. The strike was tame and straight at the goalkeeper, and most of Onana's counterparts would have caught it comfortably, but the Cameroonian contrived to parry the ball to his right and inexplicably ended up punching it in the other direction and into his own net, making it 3-2.

There was little Onana could do about Kerem Akturkoglu's thunderous equaliser, but he had already given Galatasaray two footholds in a game that United looked to have had in the bag.

Those were the cut-and-dry moments, but Onana has also been criticised for his slow reactions and poor positioning for several of the other goals United have conceded in their harrowing Champions League campaign.

He was too slow to come out and close down Wilfried Zaha's shooting angles when the former Crystal Palace forward struck Galatasaray's first goal at Old Trafford, while he allowed himself to be sat down by Icardi for the winning goal. Had he stayed on his feet, he would have saved it.

In the chaotic 4-3 defeat at Copenhagen, he could also have done better for three of the Danish side's goals. He was too slow to get down for Mohamed Elyounoussi's strike and was far too passive when Lukas Lerarger slipped in front of him to score the equaliser, which bounced off Onana's body and into the net.

Roony Bardghji's winner was struck with far more venom, but Onana could still be criticised for being beaten at his near post.
