Man Utd crash out of cup as England stars fail miserably from the spot
Wayne Rooney, Michael Carrick and Ashley Young all missed penalties as Middlesbrough knocked Manchester United out of the Capital One Cup on penalties at Old Trafford.
Boro goalkeeper Tomas Mejias saved from Rooney and Young, while Carrick blazed his effort over in between as Boro advanced to the quarter-finals with a 3-1 victory following a 0-0 draw after 120 minutes.
Louis van Gaal's side were lacklustre on the night against a side that took Liverpool to penalties in this competition last year and eliminated Manchester City in the FA Cup - and United were fortunate to survive past 90 minutes, with Daley Blind twice surviving own-goal scares.
He saw one wild hack into the net chalked off for an offside flag against Kike before he breathed a huge sigh of relief as Sergio Romero's mis-control from his back pass went narrowly wide.
Jesse Lingard struck a post in the 90th minute while Grant Leadbitter and Stewart Downing were denied by Romero in stoppage time.
The hosts should then have sealed their progress as they produced a spate of extra-time misses, Marouane Fellaini, twice, and substitute Anthony Martial guilty of missing close-range headers.
And Boro, losers of a 14-13 shoot-out epic at Anfield last season, made them pay on penalties as United joined Arsenal and Chelsea in crashing out at the last-16 stage.
The travelling contingent for this fixture stretched into five figures and they made their presence known vocally and visually by shining phone lights 10 minutes in as a show of solidarity for the job losses in the steel industry on Teesside.
They had cause to cheer when George Friend nutmegged Lingard and, moments later, the same player should have sent them in ecstasy. United failed to clear a corner from the left and Emilio Nsue's ambitious overhead kick fell straight into Friend's path, but the full-back placed his effort directly at Romero from six yards out.
For the hosts, the likes of Fellaini and Memphis Depay were doing little to prove they warranted consideration from Van Gaal in more high-profile fixtures, the latter in particular constantly losing possession with loose touches and firing a halfway line lob well over Mejias' net.
Van Gaal had clearly seen enough at the interval, taking off James Wilson for Rooney, and the hosts at least tested Mejias with a series of shots down his throat, one from Depay that he almost fumbled back over his line.
That error would have made a blooper DVD but the one from Blind 12 minutes into the second period deserved to grace a cover.
Kike was flagged offside when hitting an effort against Romero's far post and as the ball came back across the six-yard box, Blind somehow managed to slam the ball directly into the net with no one around him.
His head entered his hands but fortunately for him the linesman's flag spared his blushes.
The comedy of errors continued, though, as Romero allowed Blind's back pass to almost creep in at the back post in a manner reminiscent of ex-Aston Villa goalkeeper Peter Enckelman's howler against Birmingham.
That, coupled with Leadbitter's fierce shot at Romero, prompted Van Gaal to call for Martial too in place of the disappointing Depay with 19 minutes left.
The game was meandering towards extra-time until both sides came to life in the dying stages. Lingard, who hit the woodwork in the Manchester derby on Sunday, smashed an effort against a post before the visitors broke on the counter and Romero stood up to repel Leadbitter's lob and then Downing's drilled effort in stoppage time.
In extra time Fellaini was pushed in advance of Rooney and somehow failed to head in from close range on two occasions.
The hosts felt they should have been awarded a penalty when Martial flicked up onto Daniel Ayala's outstretched hand and the Frenchman could have prevented the flurry of spot-kicks that soon followed had he nodded in Lingard's head across in.
Rooney was the first to miss and although David Nugent blazed over, Carrick did likewise before Mejias guessed right again to deny Young and send Boro through.
