Madrid suffers after Zaza stunner
Two goals in the first nine minutes were enough to give Valencia a 2-1 win over Real Madrid that could prove important in the title race.
Valencia handed a major boost to Barcelona and Sevilla in LaLiga's title race as it beat Real Madrid 2-1 at Mestalla.
Two goals in the first nine minutes allowed Voro's side to record only its second victory over Madrid in 15 league meetings and bring the league leader's six-game unbeaten run in all competitions to an end.
Simone Zaza's spectacular turn and half-volley after four minutes had the home fans on their feet, and they were sent into raptures when Fabian Orellana scored his fifth goal of the season after a clinical counter-attack soon afterwards.
Madrid began to regain some composure and Cristiano Ronaldo headed home just before the end of a breathless first half of football to give his side some hope.
Ronaldo saw a penalty appeal turned down as Madrid built some sustained pressure after half-time, but despite enjoying nearly 72 per cent of the possession, Diego Alves went largely unworried in the Valencia goal.
A surprisingly toothless attack was unable to fashion a late equaliser, meaning Madrid remains just a point above second-placed Barca in the table, although it still has a game in hand. Valencia has climbed to 14th.
Zaza, who also scored in Monday's (AEDT) 2-0 win over Athletic Bilbao, put Valencia ahead with only four minutes played, collecting Munir El Haddadi's cross with his back to goal before blasting an unstoppable shot on the turn into the top corner, with the recalled Keylor Navas only able to stand and watch.
Five minutes later, a shell-shocked Madrid found itself two behind. Raphael Varane was dispossessed in the Valencia half and the home side raced through on the break, with Nani sending Orellana into the box to slot through the legs of Navas.
Munir saw an effort deflect over the crossbar, before James Rodriguez, who had kept his place in the starting line-up, almost squeezed Ronaldo's low cross over the line at the far post in a breathless opening 20 minutes.
Diego Alves reacted brilliantly to keep Karim Benzema's dipping effort from creeping beneath the crossbar but he could do nothing to stop Ronaldo halving the deficit before the break as Madrid made its mounting pressure count.
Marcelo was given time down the left to float a superb cross towards the penalty spot, where Ronaldo rose highest to power a header beyond Alves's right hand.
Madrid's pressure was relentless after half-time and Ronaldo had a penalty shout waved away after going to ground over an outstretched leg from Eliaquim Mangala, before Zidane turned to Gareth Bale to add some extra dynamism to his attack.
Zaza was aggrieved not to win a spot-kick of his own, having been barged aside by Dani Carvajal after an appalling piece of control from Varane, but Madrid's frustrations were nonetheless growing as Valencia broke up play by winning a number of cheap free-kicks.
Zidane urged his players forward, but despite several goalmouth scrambles in the closing stages, Madrid could not fashion any meaningful late chances to salvage a draw, meaning Barca and under-fire Luis Enrique can allow itself a little more hope in the defence of its title.
