Paris Saint-Germain reportedly approached Real Madrid last summer to determine whether it would be possible to sign Brazilian midfielder Casemiro.
The 28-year-old joined Madrid from Sao Paulo in 2013 and has developed into a key player for the Spanish champions, making 266 appearances in all competitions.
The midfielder has again been an important figure for Zinedine Zidane's side this term, contributing five goals and two assists in 26 outings.
According to Marca, PSG made an enquiry for the Brazil international during last summer's transfer window, but Madrid made it clear that he was not for sale at any price.
The report claims that Los Blancos, who are struggling financially due to the coronavirus pandemic, are also not prepared to listen to offers for the South American in the upcoming market.
Casemiro has a contract at the Bernabeu until June 2023.
