The visitors are currently 11th in the table, having picked up 25 points from 21 matches this season, while Cadiz, who were in and around the European spots late last year, have now dropped into 14th.
There is no getting away from the fact that Cadiz's recent form has been disappointing, with the newly-promoted side losing four of their last five in all competitions and each of their last three in the league, conceding 11 times in defeats to Sevilla, Atletico Madrid and Real Sociedad.
As mentioned, Cadiz have dropped from the top half of the table into 14th, now just four points clear of the relegation zone, but it has still been a solid campaign for a team back at this level for the first time since 2006.
Any position 17th or higher would be considered a successful season, with Alvaro Cervera's side determined to consolidate at this level, and they have recorded some standout results this term, notably overcoming both Barcelona and Real Madrid.
El Submarino Amarillo will be wary of suffering another defeat on Monday ahead of a trip to Barca on February 21, and the team's home form this season has been disappointing, picking up just two victories from 11 matches, suffering five defeats in the process.
Athletic, meanwhile, drew 1-1 with Valencia in the league last weekend; Hugo Guillamon's own goal had sent the Basque side ahead in the latter stages of the first period, but Gabriel Paulista came up with an equaliser for Los Che in the 65th minute.
A record of seven wins, four draws and 10 defeats from 21 matches has seen Marcelino's side collect 25 points, leaving them in 11th position in the table, although there is a strong chance that the picture will have changed by the time that they take to the field for this contest.
Athletic were also in Copa del Rey semi-final action on Thursday, playing out a 1-1 draw with Levante in the first leg of the contest at San Mames, leaving the tie delicately poised ahead of the return clash.
Los Leones will already face Real Sociedad in the 2020 Copa del Rey final at the start of April, with the match being postponed last year due to the coronavirus pandemic.
Marcelino's side must first address their inconsistent league form, though, as they have only won one of their last four in Spain's top flight, losing twice to Barca during that run.

Cadiz will be without the services of Marcos Mauro through suspension, with the centre-back receiving straight red card against Sociedad, meaning that Pedro Alcala could partner Juan Cala in the middle of the defence.
Asier Villalibre is also an option for change in an attacking position, but Marcelino is expected to resist the temptation to make wholesale changes from the Copa del Rey semi-final.
Cadiz possible starting lineup:
Ledesma; Iza, Alcala, Cala, Espino; Sanchez, Garrido, Fali, Perea; Negredo, Lozano
Athletic Bilbao possible starting lineup:
Simon; Capa, Alvarez, Martinez, Berchiche; De Marcos, Lopez, Vesga, Muniain; Williams, R Garcia
We say: Cadiz 1-1 Athletic Bilbao
Athletic's away record is actually the worst in the league this season, winning just one of their 10 matches on their travels. Cadiz have suffered three straight defeats in Spain's top flight, though, and we can see the two teams settling for a draw on Monday night.
