A trademark Cristiano Ronaldo free-kick and a late Lucas Vazquez header proved to be in vain as Real Madrid crashed out of the Copa del Rey in a 2-2 draw at Celta Vigo, losing 4-3 on aggregate.
Celta had stunned Madrid by winning 2-1 at the Santiago Bernabeu in last week's quarter-final first leg - a result that formed part of a three-game winless run for Zinedine Zidane's LaLiga leaders.
Saturday's league victory over Malaga looked to have put Madrid back on track, despite the addition of Marcelo and Luka Modric to an injury list that already features Gareth Bale and Pepe.
Madrid remained the more fancied to go through despite the first-leg result, but fell further behind late in the first half when Danilo put through his own net - not that he knew much about it.
Ronaldo powered in a free-kick after 62 minutes as Madrid sought to claw back the deficit but Daniel Wass, having played a key role in Celta's opener, placed a shot beyond Kiko Casilla with five minutes left to re-establish the cushion.
Vazquez headed home in the 90th minute to give Madrid some hope but the visitors were unable to deny Celta a second successive appearance in the Copa semi-finals, leaving the men from the capital to focus on their LaLiga and Champions League campaigns.
Celta came into this match with something to defend, and defend they did in the early stages as Madrid set about wiping out the hosts' first-leg advantage.
The home side were happy to sit deep, soak up the pressure and wait for opportunities to hit Madrid on the break, although their tactics almost backfired when Ronaldo hit the woodwork after 26 minutes.
Isco's cross from the right was perfect for the Portugal captain, who would have headed Madrid in front on the night had it not been for the lightning-quick reactions of Sergio Alvarez, who palmed the powerful effort onto his crossbar.
That near miss appeared to spark Celta into life and they should have done better when a poor Casemiro clearance presented them with a glorious opportunity to stretch their aggregate lead.
The ball fell to Iago Aspas 18 yards out but he made the wrong decision in attempting, and failing, to square for John Guidetti and the move broke down.
Celta's new attacking approach did, however, pay off a minute from the break.
Finding yet more space in the Madrid defence, Wass succeeded where Aspas had earlier failed by finding Guidetti with a squared pass.
The Swedish forward's shot hit Casilla's leg before rebounding into the net off an unsuspecting Danilo.
Madrid were desperate for a goal but they struggled to carve out any clear-cut opportunities until Ronaldo ominously stood over a free-kick some 20 yards out.
The club's record goalscorer arrowed an effort down the left-hand side of the Celta wall and beyond Alvarez, who may question the positioning of his defensive line.
Madrid had their tails up and Sergio Ramos nodded just wide from a Toni Kroos free-kick, before another Ronaldo set-piece crept just outside the right-hand upright.
Wass looked to have put the result beyond doubt when an intricate passing move eventually saw the ball pop out to him on the edge of the penalty area, picking his spot and placing a shot beyond Casilla.
Substitute Vazquez made it 2-2 on the night with a 90th-minute header, but Madrid were beaten by the clock in their desperate bid for a crucial third goal.
