A total of 20 points from nine matches has left Sociedad top of La Liga, while Cadiz have also performed above expectations this season and currently occupy sixth position in Spain's top flight.
Many predicted Cadiz to struggle this season, with the Yellow Submarine operating in Spain's top flight for the first time since the 2005-06 campaign, when they were relegated in 19th position.
A second-place finish in last season's Segunda Division allowed them to return to this level, and Alvaro Cervera's side have given an excellent account of themselves in the early months of the campaign.
Indeed, a record of four wins, two draws and three defeats from nine matches has seen them collect 14 points, which is enough for sixth spot in the table, just two points behind fourth-placed Real Madrid.
Cadiz have picked up some eye-catching results this season, notably a 1-0 victory away to Real Madrid after the last international break, but they will enter this weekend's clash off the back of a 4-0 loss at Atletico Madrid.
Sociedad, meanwhile, are absolutely flying in the league, winning each of their last five against Getafe, Real Betis, Huesca, Celta Vigo and Granada, scoring 16 times in the process.
Sociedad have also been in good form in the Europa League, picking up six points from their three group matches, although they did lose 1-0 at home to Napoli at the end of last month.
The White and Blues have not claimed a top-four spot in La Liga since the 2012-13 campaign but will certainly have their eyes on a potential return to the Champions League next season.
Imanol Alguacil's side are actually on a run of four straight away wins in all competitions, while they are unbeaten in their last six La Liga matches on their travels.

Cadiz will be unable to call upon key forward Anthony Lozano this weekend as the 27-year-old is currently self-isolating following a positive coronavirus test.
Negredo, who has scored twice in the league this term, is allegedly winning his race to overcome a muscular problem in time for the contest, while Sanchez and Fernandez will also hope to be involved.
David Silva has been in excellent form for the Basque outfit since arriving from Manchester City over the summer, and the Spaniard should again feature in the middle of the park.
Cadiz possible starting lineup:
Ledesma; Akapo, Cala, Fali, Espino; Garrido, Fernandez, Jonsson; Izqueirdo, Negredo, Sanchez
Real Sociedad possible starting lineup:
Remiro; Zaldua, Elustondo, Zubeldia, Monreal; Merino, Zubimendi, D Silva; Portu, Willian Jose, Oyarzabal
We say: Cadiz 1-2 Real Sociedad
Cadiz will be determined to bounce back from their heavy defeat to Atletico before the international break, but it is difficult to look past Sociedad due to their excellent run of form; we are expecting a relatively tight match but still expect the visitors to pick up another three points.
