Real Madrid ensured it remains at least six points ahead of title rival Barcelona at the top of La Liga after a comfortable 5-1 victory over Osasuna at the Reyno de Navarra.
Karim Benzema netted the first of the night with a stupendous volley before Cristiano Ronaldo and Gonzalo Higuain extended Madrid's lead before the break. Osasuna clawed a goal back early in the second half through Nino, but it was in vain as Ronaldo and then Higuain completed the rout, ending the Navarrans' six-game unbeaten streak.
Benzema fired Los Blancos ahead with a truly remarkable strike, connecting with Cristiano Ronaldo's deep cross. The ball hung in the air allowing the Frenchman to set himself before showing perfect technique as he unleashed an unstoppable volley into the opposite corner.
In pursuit of a second, Madrid counterattacked at pace ending in Ronaldo's dipping effort narrowly missing the target. Los Blancos had manufactured the chance after the referee had let play continue following Xabi Alonso's crunching tackle, a challenge that Mendilibar contested resulting in the Osasuna coach being sent to the stands.
As the quality of play subsided the Navarrans drew a number of fouls, one of which saw Sergio Ramos harshly cautioned, ruling the defender out of Valencia's visit to the Bernabeu.
Ronaldo then explosively came onto the stage as he netted his first ever goal at the Reyno de Navarra. Picking the ball up all of 35-yards from goal, the Portuguese international took one look before rifling a stunning effort into the top corner.
And Mourinho's side found a third not long after when Xabi Alonso's precise pass found Higuain. The Argentine international, clean through, provided a cutely clipped finish over Fernandez to net his 100th Real Madrid goal five minutes before the break.
Dejan Lekic was introduced for the second half as Osasuna looked to reduce the three goal deficit, which the club did after just two minutes. Roversio won the ball deep in Real Madrid territory before crossing toward the far post where Nino was on hand to send a bullet header past Casillas.
Higuain would have reestablished Madrid's three goal lead after rounding Fernandez, but for a moment of pure comedic value. Ronaldo collided with the Argentinean as both men looked to provide the finishing touch, but instead they watched in despair as the ball went behind for a goal kick.
Osasuna remained in the ascendancy as the half progressed but Madrid always threatened on the break, and Los Blancos were awarded a fortuitous free kick on the edge of the area after a fluent counter. Ronaldo stepped up and, courtesy of a deflection, registered his 37th La Liga goal.
Ronaldo then turned provider with beautiful footwork on the wing, as Madrid put the game to bed. The former-Manchester United man danced past his marker before presenting Higuain with the easiest of headers to double his goal tally for the evening.
As the game drew to a close Roland Lamah was shown two consecutive yellow cards as Osasuna finished the match with 10 men. Madrid returns to Champions League action in midweek against APOEL, while Osasuna will be looking to get back on track when it faces Rayo Vallecano.
