Real Madrid are reportedly desperate to sign a replacement for Cristiano Ronaldo, and are now willing to spend €300 million on their preferred target before the window closes, but only on one condition.
Click through the gallery above to see some players who are still linked with a switch to Real in this window.
Spanish publication Sport has suggest that president Florentino Perez still wants to dive into the transfer market, which closes on 31 August for LaLiga clubs, for a "Galactico".
The club's 4-2 UEFA Super Cup defeat to crosstown rivals Atletico Madrid earlier this week exposed some of Real's weaknesses and has caused alarm bells to ring at the Santiago Bernabeu.
As a consequence, Perez is now reportedly prepared to splash the cash on Neymar, but he knows the Brazilian superstar will only become available if Paris Saint-Germain are sanctioned for failing to comply with Financial Fair Play regulations.
UEFA are still investigating PSG over certain sponsorship deals that appear to be above market value and are double or even triple what other teams have received.
Payments made by Qatar National Bank are also being reviewed as they are believed to be a hidden part of said sponsorship deals, according to Sport.
The ruling of UEFA's appeal committee is expected at the end of August and, while PSG believe they have everything in order and will not be punished, Real will be ready to sign Neymar for €300 million (R5 billion) should UEFA rule against the French giants.
However, even if Neymar does not become available, Perez has reportedly put aside €50 million (R846 million) for a new forward, with Mauro Icardi, Rodrigo and Timo Werner all linked with the club, although all of them would likely cost more than €50 million.
Aside from a striker, Real manager Julen Lopetegui has reportedly also asked for a centre-back, and Marcos Alonso has been linked with the Spanish giants since.
