Atletico Madrid want a player in exchange plus huge cash for long-time Arsenal target Thomas Teye Partey.
The 26-year-old has been constantly linked with a move away from the Wanda Metropolitano.
Arsenal boss Mikel Arteta is a long-time admirer of the talented Ghanaian midfielder and is keen to bring him to London.
However, Atletico Madrid is now beginning to get used to the idea of losing the Ghanaian star, one of its pillars in the current season.
Reports have claimed on Tuesday that the Spanish club want Shkodran Mustafi, Matteo Guendouzi or Alex Oxlade-Chamberlain in a player exchange plus cash before allowing their prize asset to leave.
The Atletico Madrid midfielder has a £43.5 million release clause in his contract at the Spanish club.
