FANS blasted Andre Onana as Manchester United conceded directly from a corner for the SECOND time in eight days.
It peaked a crazy start to the second period for the Red Devils as Bruno Fernandes had just seen red for his second silly booking.
Matheus Cunha swung over a corner that went straight into the far corner as the struggling hosts went in front on 58 minutes - with Hee Chan Hwang then clinching a 2-0 win in stoppage time.
Matt Doherty and Santiago Bueno had appeared to box Onana in.
And as the United keeper focused on those two Wolves players, he neglected Cunha's corner sailing over him and into the net.
Stand-in Red Devils' stopper Altay Bayindir suffered the same humiliation days earlier in last week's 4-3 League Cup quarter-final defeat at Tottenham.

But there was little sympathy for Onana from fans after his Boxing Day blunder in the Premier League.
One posted: "I’ve no more words for Onana" while another posted: "Abysmal."
A third just put: "Our two keepers conceded from straight corners in one week."
United have now let in ten set-piece goals this term.

Even more amazingly, that's eight such goals breached in the past seven games under new boss Ruben Amorim.
And former United captain Harry Maguire even admitted opposition teams are targeting dead-ball situations against the Red Devils.
He said: "Set plays are so important in football matches and they decide games.
"A lot of the games when they are tight and they're 50-50 are decided by the first goal and the first goal has been a set play far too many times against us and it's disappointing.
"I think teams now are obviously probably maybe targeting our area of set plays.
"The strange thing is I don't think we are conceding many chances from them.
"They've had a few set plays tonight and we've dealt with them really well then they've gone and scored from one."
Asked how United can fix the set-piece problem, Maguire added: "Work, work, work more on the training pitch.
"It's hard work. Keep the belief and things will change, I know that.
"We have players who can defend the box well and it will change, we've just got to stick together."
Wolves boss Vitor Pereira amazingly revealed he planned for his team to score directly from a corner.
He said: "Of course we analyse every match and try to understand the spaces we can explore."
United defensive legend Rio Ferdinand was more stunned than most.

Ferdy normally has plenty to say about big incidents but this time he could only post: "No comment."
A fan responded to the former England star's message with: "Seriously we haven't learnt anything in these past weeks on set pieces. This is becoming annoying."
