The veteran defender has returned to Europe after coming off contract with Liga MX's Monterrey.
Ramos is eager to play on this season with the aim of breaking into Spain's World Cup quad.
He had a previous spell with Sevilla and Estadio Deportivo says Ramos already serves an advisor and has a small number of shares. He is now considering becoming an investor in the future sale.
For the moment, Ramos has only “sought information on his options should he decide to acquire a significant share".
Ramos began his pro career with Sevilla before moving to Real Madrid, where he won everything in the game. After a spell with PSG, Ramos had a shorter stint with Sevilla before leaving for Monterry last year.
