Lionel Messi is arguably the biggest name on the list and could become a free agent by the end of June.
He wanted to leave FC Barcelona ahead of the 2020/21 season already but was forced to stay by then-president Josep Maria Bartomeu.
Latest reports claim Messi will wait for the outcome of the club's presidential elections later in January before making a decision on his future.
However, Manchester City and Paris Saint-Germain are said to be keen on signing him for free.
Meanwhile, David Alaba is another superstar who could join a new club on a free transfer.
The 28-year-old has failed to agree to a contract extension with Bayern Munich and is believed to be in talks with several top teams.
It is understood that Real Madrid are the frontrunners for his signature, but Alaba's move might be linked to the future of Sergio Ramos.
