The Catalan giants enter the competition as the reigning La Liga champions, while Osasuna are competing in the Super Cup after finishing runners-up in last season's Copa del Rey.
Match preview
Barcelona head to Saudi Arabia looking to retain the trophy they won last season after they followed up a penalty shootout win over Real Betis with a 3-1 victory against rivals Real Madrid in the final.
That success may have represented the first time Barcelona had won the competition since the four-team format was introduced in 2018-19, but the Catalan giants are the record winners of the Super Cup, having lifted the trophy on 14 occasions.
After ending 2023 with a 3-2 win over Almeria, Xavi's side have begun the new year with a couple of victories, scoring a stoppage-time winner to beat Las Palmas, before they claimed a 3-2 Copa del Rey win against fourth-tier Barbastro thanks to goals from Fermin Lopez, Raphinha and Robert Lewandowski.
Although they can be pleased with the fact they have won three competitive games on the bounce, Barcelona may be frustrated by their lack of convincing results, with their last 12 victories coming by a one-goal margin.
While Xavi may want to see his side produce a dominant performance sooner rather than later, his main focus will be on guiding the Blaugrana to their third Super Cup final in four seasons.
They will certainly fancy their chances of beating Thursday's opponents, having won six of their last seven games against Osasuna (D1), including a 2-1 win in September's league clash when Lewandowski netted an 86th-minute penalty to seal all three points.
Osasuna are looking forward to their first-ever appearance in the Super Cup after experiencing a memorable run to last season's Copa del Rey final, before their dream of winning their first major trophy was ended by a 2-1 defeat to Real Madrid.
Los Rojillos also achieved a seventh-place finish last term, but they have struggled to match that success this time around, having picked up 22 points from 19 league matches to leave them in 12th position at the halfway stage of the campaign.
They did at least add three more points to their tally in their most recent league outing against Almeria, before they recorded an extra-time victory over second-tier Castellon courtesy of Jose Arnaiz's 118th-minute winner.
Although they have failed to score more than one goal in seven of their last eight matches, Osasuna have proven to be a tough team to break down in recent times, keeping three clean sheets in their previous four outings.
As the underdogs in the competition, Osasuna will need all that defensive resilience if they are to trouble Barcelona and secure their place in Sunday's final against either Real Madrid or Atletico Madrid.
However, sealing a spot in the final will be easier said than done, having failed to beat Barcelona in over three years since they recorded a 2-1 away league victory in July 2020.
