One factor in the negotiations is the presence of a €20 million release clause in Mosquera’s contract, which Valencia insist must be met by any potential suitor. Arsenal, however, are attempting to strike a deal slightly below the release figure, ideally by structuring payments over time rather than paying the full sum upfront. The Gunners are hopeful that the player's willingness to join them will increase their leverage, but Valencia are showing no signs of budging just yet.
