The Spanish football federation (RFEF) said on Saturday that there would be no restrictions on players from outside the European Union for the Super Cup, despite only three being allowed in squads for league matches.
Barca, therefore, could easily field only three non-EU players rather than risking the match.
According to the rule governing the game in Spain, only three non-EU players are allowed in each La Liga matchday squad.
Sevilla qualified for the match as last season's Copa del Rey runners-up, after Barcelona won the league and cup double.
"The club's legal department is studying the matter and should FC Barcelona submit a team with more than three non-EU players, it would present possible ground for withdrawal on account an improper line-up".
This is also the first year that the trophy will be decided over one game, with the Super Cup previously a two-legged affair.

Barca have taken four non-EU players to Morocco, including defender Marlon.
It was reported earlier this week that Barcelona were in the process of acquiring a Portuguese passport for midfielder Philippe Coutinho in order to free up a third non-EU playing spot in their squad and that process is believed to have been completed.
