With just weeks of domestic and European football left of the 2020/21 season, Real Madrid could still end their season with two major trophies and complete a historic double. At the same time, it is just as likely they may lose it all.
Following a disappointing goalless stalemate against Real Betis in La Liga, Los Blancos turned their attention to Thomas Tuchel and his revolutionised Chelsea side in the semi-finals of the Champions League.
With many questioning Zinedine Zidane's decision of a 3-5-2 formation before the game, Madrid were rocked when Christian Pulisic fired the London outfit ahead in the Spanish capital. They valiantly fought back through a customary Karim Benzema equaliser, though, leaving it all to play for in the second leg.
Before Zidane's side travel to London for the emphatic second-leg at Stamford Bridge, they must first stabilise their domestic form, as La Liga's fascinating three horse race for the title rolls on with just five games to play.
With less than three points separating Real, their fierce inner-city rivals Atletico and Clasico foes Barcelona, a late slip up from either side will be monumental in deciding the fate of Spanish football's most prestigious prize.
Awaiting Los Blancos next in their nervy rollercoaster of a final run in is a mid-table Osasuna side who frustrated them in the previous fixture in Pamplona, in a goalless draw at the El Sadar Stadium.
Jagoba Arrasate's side have won three of their previous five games and remain on course for a top half finish should they emulate this form throughout the back end of the season, but this is much easier said than done with a title-hungry Real Madrid stood in their way.
Los Blancos haven't lost to Osasuna in their previous thirteen games, winning 10 and drawing three, their last loss against Los Rojillos came in the 2010/11 La Liga season, which finished 1-0 at the El Sadar Stadium.
Of the 79 encounters between the two sides, Real have emerged victorious in 49 of them and possess a win percentage of 62%, Osasuna have registered 13 wins (16%) and 17 draws have been played out in the fixture.
Los Blancos also retain superiority on the goalscoring front, having bagged 172 of the 248 that have been scored, meaning they have scored 69% of all goals between the teams and 96 more than Osasuna.
Legendary Portuguese forward, Cristiano Ronaldo is the record goalscorer in the fixture with 12, other iconic Madrid players who have enjoyed goalscoring spells against Los Rojillos include Ferenc Puskas and Alfredo di Stefano.
Madrid's last defeat against the Pamplona outfit at the Santiago Bernabeu in all competitions came in April, 2004 and finished 3-0 to the visitors, they haven't lost at home to Los Rojillos in their last 13 meetings in the Spanish capital.

Vinicius Junior has proven himself to be an important asset at the Santiago Bernabeu this season.
Los Blancos haven't lost to Osasauna in over a decade, and will be determined to extend their undefeated run to continue their title challenge.
Real Madrid 7-1 Osasuna
November 6, 2011
A Cristiano Ronaldo hat-trick inspired a superb thrashing at the Santiago Bernabeu for Jose Mourinho's side as Real Madrid decimated Osasuna 7-1 to extend their lead at the summit of the league.
Despite opening the scoring through a header from their Portuguese talisman, Real were rocked when Osasuna equalised just eight minutes later through Ibrahima Balde's right-footed strike, but their worries were alleviated when Pepe headed home to regain their lead.
Gonzalo Higuain put some distance between the two sides on the 40 minute mark, finessing a right-foot strike into the top corner of Fernandez's goal and Ronaldo was on hand to convert a penalty, ten minutes into the second.
It was from that moment on that Madrid began to run riot in the Spanish capital. Ronaldo completed his hat-trick with a wondrous looping header, and Karim Benzema bagged a late brace of left-footed strikes to complete the 7-1 decimation.
Real Madrid 5-2 Osasuna
September 10, 2016
Real triumphed 5-2 over ten-man Osasuna at home, to maintain their 100% start to the season after three games.
Following months on the sidelines with a knee injury sustained in Portugal's Euro 2016 winning campaign, Ronaldo made his first start of the season, and it didn't take him long to get back in the goals upon his return - as he gave the hosts the lead after just six minutes.
Danilo doubled Los Blancos' lead after 40 minutes, punishing Osasuna for a number of missed chances in the first half, as Sergio Ramos headed home a Toni Kroos corner in added time to make it three.
Another corner from Kroos created Real's fourth, as Pepe was the man to meet the German's ball and head home, Luka Modric fired home a fifth eight minutes later to wrap up a brilliant performance from Los Blancos.
Despite scoring two late consolation goals, Los Rojillos were reduced to ten men when Bonnin Vasquez received his marching orders following a second bookable offence, as Zidane's side cruised to victory.
Osasuna 1-4 Real Madrid
February 9, 2020
Despite falling behind in the first-half, Los Blancos emphatically responded with four goals of their own, maintaining their three point lead atop of the La Liga table in a comfortable victory.
Jagoba Arassate's side found themselves ahead after just 14 minutes - a superb diving header from Unai Garcia flew past Sergio Hererra following a thunderous corner from Ruben Garcia.
Unfortunately for Los Rojillos' their hard work was undone before the half time whistle had been blown, as Real struck twice in five minutes to turn their fortunes of the game in their favour.
Isco levelled proceedings with an inventive volley in the Osasuna box before Sergio Ramos leapt the highest to head home from a corner to put Zidane's side in front.
Following a closely contested second half, Lucas Vazquez put the game beyond the reach of Los Rojillos in the final five minutes before Luca Jovic came off the bench to add insult to injury in stoppage time.
