Los Blancos are currently second in Spain's top flight, level on points with the champions Barcelona, while Espanyol sit inside the relegation zone having struggled for results in the opening months of the season.
Madrid have not been without their problems this season but results on the field, particularly in recent weeks, have been impressive. There were suggestions earlier this season that Zinedine Zidane's position as head coach was already under threat, although the rumours appear to have dissipated.
Both Madrid and Barca have a game in hand on the rest of La Liga following the postponement of El Clasico, but Spain's two biggest clubs are currently first and second with 31 points to show from their 14 league matches this term.
Los Blancos have won their last three against Eibar, Real Sociedad and Alaves since dropping points against Real Betis on November 2, while they are unbeaten in Spain's top flight since a 1-0 loss at Mallorca on October 19.
Madrid have also gone four games unbeaten in the Champions League, booking their spot in the last-16 stage of the competition ahead of their final group match away to Club Brugge on Wednesday night.
Zidane's team have four more league matches before the winter break kicks in on December 22, including a trip to Barca on December 18, which could have a big say in which team leads the division heading into 2020.
Espanyol have been present in La Liga since being promoted at the end of the 1993-94 campaign, but there is a genuine fear that the Catalan outfit could drop into the second tier come the end of the current season.
The White and Blues finished seventh in La Liga last term, while they have not been lower than 14th since 2005-06. As a result, the fact that they have struggled so badly this season has come as a huge surprise.
Two wins, three draws and 10 defeats – that is how Espanyol have performed in the league this term. A total of nine points has left them in 19th spot in the table, while they have the worst goal difference in the league with minus 18.
No team has conceded more times in La Liga this season, while they are already five points off the safety of 17th position, which is a concern at this stage, particularly heading into this particular contest.
Pablo Machin's side have booked their spot in the knockout round of the Europa League with a match to spare but have only picked up one league victory since the middle of September, losing four of their last five.
Real Madrid form: LWDWWW
Espanyol form: WLLLDL
Madrid will again be without the services of Marco Asensio, James Rodriguez and Lucas Vazquez , while Nacho is also unlikely to feature despite recently returning to training following a knee problem.
Eden Hazard has also been ruled out for the remainder of 2019 after being diagnosed with a stress fracture in his right ankle, meaning that the Belgian will also miss El Clasico later this month.
Thibaut Courtois, Raphael Varane and Federico Valverde are also in line for recalls having been left out of the XI against Alaves, while Ferland Mendy is expected to replace Marcelo, who is struggling with a calf issue.
Real Madrid possible starting lineup: Courtois; Carvajal, Varane, Ramos, Mendy; Valverde, Casemiro, Kroos; Rodrygo, Benzema, Isco
Espanyol possible starting lineup: Diego Lopez; Calero, Espinosa, David Lopez; Roca; Pedrosa, Darder, Melendo, Avila; Wu, Calleri
We say: Real Madrid 3-0 Espanyol
It is difficult to imagine a scenario where Madrid do not pick up all three points in this match. Zidane's side are on a bit of a run at the moment and we expect them to record a comfortable victory at the Bernabeu, despite the fact that a number of key players will be absent for Saturday's affair.
