According to various reports, the midfield maestro will take home around £4.1m should he agree to a new deal by the Los Rojiblancos.
This will, in turn, raise his buyout clause to at least £91m.
Partey has been an instrumental figure for the Diego Simeone this term, putting in a stellar shift in their two-legged champions quarterfinals qualification over Liverpool.
He has been linked with moves to English pair, Arsenal and Manchester United over the period.
The Ghanaian international has three years remaining on his current deal which has a reported buy-out clause of £42m.
Should the two parties fail to agree on a new deal, it’s increasingly likely the Ghanaian midfielder will depart the Metropolitan stadium on a cheap.
