The Basque outfit are currently on a run of four straight league victories, including back-to-back 4-1 wins over Huesca and Celta Vigo, while they have also beaten Getafe and Real Betis 3-0 since the start of last month.
Sociedad's domestic form is even more impressive considering that they have already played three times in the Europa League this term, picking up two wins, including a 1-0 home success over AZ on Thursday night.
La Real finished sixth in La Liga last term and have not actually claimed a top-four spot since 2012-13; the early indications are that Alguacil's side could seriously challenge for a Champions League position this season, though, and a win this weekend would leave them in an excellent spot ahead of the international break.
Granada, meanwhile, were also in Europa League action on Thursday night, moving onto seven points in their section courtesy of a 2-0 victory away to Omonia Nicosia.
Like Sociedad, Granada's league form has also been strong, collecting eight points from their last four matches to sit sixth in the table, just three points behind their opponents this weekend.
A record of four wins, two draws and one loss from seven domestic matches represents an excellent start, and Diego Martinez's will be eyeing another positive result on Saturday afternoon.
El Grana impressively finished seventh in La Liga last term on their return to this level, and it would be some story if they pushed towards the Champions League positions in 2020-21.
The Red and Whites actually recorded a 3-2 victory over Sociedad when the two teams last met in July, but La Real have won five of their last six encounters in Spain's top flight.

Portu and Oyarzabal will keep their spots in attacking positions, though, while David Silva is again expected to line up as an advanced midfielder for the Basque club.
Real Sociedad possible starting lineup:
Remiro; Zaldua, Elustondo, Le Normand, Munoz; Merino, Zubimendi, Silva; Portu, Willian Jose, Oyarzabal
Granada possible starting lineup:
Silva; Foulquier, Duarte, Sanchez, Neva; Montoro, Milla, Herrera; Suarez, Molina, Kenedy
We say: Real Sociedad 2-1 Granada
Both teams have been excellent in the early stages of the 2020-21 campaign, and it is shaping up to be a fascinating battle in San Sebastian. Sociedad's league form, in particular, has been brilliant, and we fancy the Basque outfit to pick up another three points on Sunday afternoon.
