Imanol Alguacil's side have won each of their last six matches in all competitions, including their last three in the league against Sevilla, Osasuna and Almeria to cement themselves in the top four.
Real Sociedad have also progressed in the Copa del Rey, with the Basque outfit due to take on Mallorca in the last-16 stage of the competition on January 14, while they have qualified for the knockout round of the Europa League, so it will be a busy few weeks for the club.
The White and Blues have finished sixth, fifth and sixth in their last three La Liga campaigns, failing to finish in the top four since 2012-13, so it would be an impressive achievement to return to the Champions League spots.
