The Spanish champions are now just one point behind league leaders Real Madrid in the table, while Eibar currently occupy 16th spot, just three points clear of the relegation zone.
Barca announced on Thursday that they had completed the signing of Martin Braithwaite from Leganes, with the Dane penning a contract at Camp Nou until June 2024. Having been granted the opportunity to make an emergency signing following Ousmane Dembele's injury, Braithwaite has arrived in Catalonia.
The 28-year-old could actually make his debut for his new club against Eibar, although it seems more likely that the former Middlesbrough attacker will be on the bench for the league contest.
Quique Setien's side have had their problems in recent weeks but have posted three straight wins in the league since a 2-0 loss at Valencia. Indeed, they overcame Levante and Real Betis before picking up three much-needed points at home to high-flying Getafe last time out.
The fact that Real Madrid dropped points against Celta Vigo last weekend means that the gap from first to second is now just a single point, and the two Clasico rivals will meet at the Bernabeu on March 1.
Barca will also travel to Napoli for the first leg of their last-16 Champions League tie on Tuesday night, and Setien will hope that Lionel Messi will continue to put in star performances despite the fact that the Argentine has not scored in any of his last four league outings.
Eibar have performed above expectations in La Liga over the last three campaigns, posting 10th, ninth and 12th in their last three seasons at this level of football. The Basque side are very much in a relegation battle at this stage, though, with only three points separating them from the bottom three.
The Gunsmiths have not actually triumphed in the league since beating Atletico Madrid 2-0 on January 18, drawing against Celta Vigo and Real Betis in addition to losing at Alaves last time out.
Jose Luis Mendilibar's side have only picked up one league victory on their travels this season, meanwhile, and have shipped 13 goals in their last three visits to Barca in Spain's top flight.
The visitors should be well rested, though, as they have not actually played since February 7. Indeed, their clash with Real Sociedad last weekend was postponed due to "high levels of chemical compounds detected in the air" around the Ipurua following a fire the day before.

Braithwaite could make his debut having joined on Thursday, although it seems more likely that the Dane will be named on the bench for this weekend's clash.
Clement Lenglet is also available for the hosts having served a one-game domestic ban.
Barcelona possible starting lineup:
Ter Stegen; Semedo, Pique, Lenglet, Firpo; De Jong, Busquets, Vidal; Fati, Griezmann, Messi
Eibar possible starting lineup:
Dmitrovic; Arbilla, Burgos, Oliveira, Cote; Cristoforo, Diop; Leon, Exposito, Orellana; Enrich
We say: Barcelona 2-0 Eibar
It is difficult to make a case for Eibar this weekend considering their away form this season. Barca are far from perfect at the moment but should still have too much for their Basque opponents on the afternoon.
