The hosts will enter the contest off the back of a 1-0 home defeat to Real Sociedad on Thursday, while Elche picked up an impressive point against the champions Real Madrid on Wednesday.
Only Real Betis (nine) have lost more La Liga matches than Athletic (eight) this season, but the Basque outfit have picked up 18 points from five wins and three draws to occupy 12th position in the table.
Gaizka Garitano's side have certainly had their problems this season and will enter this weekend's contest off the back of a disappointing 1-0 home defeat to Sociedad on Thursday.
Athletic are only one point behind ninth-placed Cadiz as things stand, though, and could potentially push for a position in the top half of the table over the next few months.
The Basque outfit will be even more determined to return to winning ways on Sunday considering that their next two in La Liga are at home to Barcelona and away to Atletico Madrid.
Athletic recorded a 3-2 victory when these two teams last locked horns in May 2015, but Elche ran out 2-1 winners when they travelled to San Mames earlier in the season.
Elche, as mentioned, will enter Sunday's contest off the back of a 1-1 draw with Real Madrid; the champions took the lead in the 20th minute of the contest through Luka Modric, but a second-half penalty from Fidel meant that the points were shared at Estadio Manuel Martinez Valero.
Los Franjiverdes secured a return to the top flight by advancing through the Segunda Division playoffs last season, and they are operating at this level for the first time since 2014-15.
All things considered, it has been a solid start to the season for the promoted club, winning three, drawing seven and losing four of their 14 matches to collect 16 points, which has left them in 15th position.
Jorge Almiron's side have failed to win in the league since October 23, though, and suffered defeats to Granada and Atletico before drawing their last two at home to Osasuna and Real Madrid.

Athletic will again be without the services of Yeray Alvarez and Peru Nolaskoain through injury, while Unai Lopez had to be substituted against Sociedad due to a knee problem and will also be unavailable.
Garitano is expected to resist the temptation to make wholesale changes this weekend, meaning that Asier Villalibre, Inaki Williams and Alex Berenguer should all feature in the final third of the field.
Athletic Bilbao possible starting lineup:
Simon; Capa, Nunez, Martinez, Yuri; Vesga, Vencedor; Berenguer, R Garcia, Williams; Villalibre
Elche possible starting lineup:
Badia; Barragan, Verdu, Josema, Sanchez; Rigoni, Guti, Marcone, Rodriguez, Fidel; Boye
We say: Athletic Bilbao 1-1 Elche
Athletic will view this match as the ideal chance to return to winning ways, but Elche have proved difficult to beat in the league this season, losing just four of their 14 matches; we are finding it tough to pick a winner in this contest and have therefore settled on a 1-1 draw.
