He told Mundo Deportivo: "It's just that we don't see it as necessary. There will be some tweaks."
Laporta added Barcelona could make "one or two additions" to the squad but warned a big-name signing could disrupt the current team.
"I do not see it necessary to make an investment that could distort what we are building, which is a balanced team," he added. "Next year we will have Gavi again, which gives energy. Pedri and Frenkie are world-class players like all the ones we have."
