Two first-half goals in two minutes from the Argentine duo put Los Blancos en route to all three points as Jose Mourinho completed a century of wins in charge of the clubReal Madrid made it five Liga games without defeat as it coasted to a straightforward 4-0 victory over Zaragoza at the Santiago Bernabeu.
In front of a rather hushed set of fans, two goals in quick succession, courtesy of Gonzalo Higuain and Angel di Maria, ensured that Los Merengues took a two goal lead into the break.
The visitors were resurgent in the second half but Michael Essien and Luka Modric added a pair of late goals as Jose Mourinho earned his 100th win in charage of Madrid.
The game began at a relatively tepid tempo, with Zaragoza not afraid to push men forward and attack Los Blancos.
Yet Madrid looked more likely to score and after Di Maria wasted an early chance, he clipped a fantastic ball up to Cristiano Ronaldo in the 14th minute. The Portuguese got between the defenders and headed it at goal but was unable to work Roberto Jimenez in the Blanquillos' goal.
The relatively muted atmosphere in the Bernabeu almost turned to stunned silence six minutes later though. Sergio Ramos' poor clearance fell straight to Helder Postiga but the defender's blushes were spared as Iker Casillas saved the Portuguese's effort with his legs.
Typically, Madrid countered with intent and in the 23rd minute it took the lead. Roberto did well to stop Raul Albiol's header from finding the back of the net but there was nothing he could do as Higuain lashed in the rebound from inside the six yard box.
The onslaught continued as it only took two minutes for the hosts to double their lead. Again, Roberto saved the initial effort but Di Maria fired home at the second time of asking.
Madrid was exploiting acres of space on the right and Ronaldo came close to making it three before the half hour mark, though his driven cross-goal effort flew narrowly wide of the post.
The hosts remained on top after the break but some resilient defending from the Blanquillos ensured that the deficit remained at two.
Zaragoza began to get a footing in the game but was denied a goal by a fantastic Casillas save in the 58th minute. Victor Fernandez shifted the ball onto his left foot and curled a 20-yard effort for the far corner, only to see the keeper claw it aside.
The Spain international's goal came under real threat again moments later as Paco Montanes tested him with a long range strike before Jose Mari's deflected effort cannoned back off the crossbar with 25 minute remaining.
The visitors did manage to get the ball in the back of the net after a brilliant finish from Postiga but the goal was disallowed for a contentious offside decision.
Ronaldo rattled the bar with a swerving 85th-minute free kick but the third goal came two minutes from time as Essien slotted home following a swift counterattack.
There was still time for another as, in the second minute of stoppage time, Modric drilled a low effort from the top of the box past Roberto to add some gloss to the scoreline.
Victory sends Madrid above Malaga and into third position, however, it still sits a daunting eight points adrift of league leader Barcelona.
