With both sides flying high towards their respective league ambitions, this clash makes for an unusually enticing reading.

Getafe manager Jose Balados will be without forward Amath Ndiaye Diedhiou, who is set to be out for the remainder of the campaign after undergoing knee ligament surgery.
Barcelona boss Valverde is sweating on the fitness of Malcolm and Samuel Umtiti, after missing a handful of games before the New Year.
Malcolm, linked with a move away from the Spanish giants, hasn't featured since their 2-0 win over Villarreal on 2 December. Meanwhile, winger Rafinha is not expected to return this season after rupturing his cruciate in November.

Head to Head Record
Getafe have not beaten their opponents in their last 11 league meetings - last defeating the 25 time champions in a 1-0 home victory in 2011.
However, El Gata halted a four game losing streak in February's corresponding fixture - holding the Blaugrana to a goalless draw at the Camp Nou.
An eighth place finish last term would have delighted the Azulones faithful after their promotion back to the top flight in 2016-17 - let alone their current lofty position.
Sitting a point adrift of Real Betis in the last Europa League spot, Getafe are currently unbeaten in five league games.
Enjoying their best run of form this term, the Catalan giants look on course to scalp a 26th La Liga honour ahead of their beleaguered rivals Real Madrid. Netting 13 goals in their last four, normality has been restored after an indifferent run of results.
The ever-influential Lionel Messi has been involved in a prolific 25 of his sides 48 goals this campaign (15 goals and 10 assists).
Here's how each side has faired in their last five fixtures:
Girona 1-1 Getafe (21/12)
Barcelona 2-0 Celta Vigo (22/12)
Getafe 1-0 Real Sociedad (15/12)
Levante 0-5 Barcelona (16/12)
Leganes 1-1 Getafe (07/12)
Barcelona 1-1 Tottenham (11/12)
Getafe 5-1 Cordoba (04/12)
Espanyol 0-4 Barcelona (08/12)
Getafe 3-0 Espanyol (01/12)
Barcelona 4-1 Cultural Leonesa (05/12)
Whilst both sides come into Sunday's meeting in good form, the Blaugrana's array of talent pits them as favourites as they seek a 12th win of the campaign.
Prediction: Getafe 1-3 Barcelona
