Laporta said signing Messi to a new contract did not depend on the outcome of an audit the club is carrying out to find out the exact state of its finances.
The 33-year-old Messi has led Barcelona to four Champions League titles and 10 Spanish league titles.
The Super League, which provoked a backlash by other clubs, fans and authorities around Europe, was announced by a dozen top clubs in England, Spain and Italy on Sunday.
Even though Messi avoided the burning question of his plans, his great game will raise hopes for Barcelona fans of the soccer great staying at Camp Nou.
The 58-year-old will return after holding off competition from Victor Font and Toni Freixa, the other two candidates to gain enough support to make the final stage.
