This comes after Salah took to Twitter earlier on Sunday to express his disappointment towards the way the EFA handled the image rights' dispute, which saw the country's football governing body use the player's image on the Egypt team plane.
"The important thing is that he and his teammates stay in a good psychological condition and fully focused ahead of the World Cup", the statement read. "Especially since Egypt is going to participate in the 2018 World Cup", Abdel-Aziz tweeted hours after Salah's.
Salah, who has been rampant for Liverpool this season, notably against AS Roma in last week's first-leg Champions League semi-final, is now football's hottest property.
This is problematic for Salah because he already has a sponsorship deal with telecommunications company Vodafone, while the Egypt national side are sponsored by their rivals WE.
One can only assume that both parties want to resolve the issue before the big tournament in Moscow, but Salah's agent, Ramy Abbas, has stoked the flames further, emphasising that "time is of the essence".
In a message sent out from his Twitter account yesterday in Arabic, Salah stated that he was "insulted" by the act, and admitted that he hoped the FA would be "classier than this".
"We were promised a solution and God willing the issue is on its way to being resolved", Salah tweeted late on Sunday, while also thanking his fans for their "unreal" support. Nothing! Complete silence! What's the plan?!
"Mohamed Salah is an example for Egypt's youth who love and are loyal to their homeland and he is representing his country overseas in the best image".
Salah's camp argue that the Egyptian FA and agency Presentation, a major player in the Egyptian sports landscape, don't have the right to use Salah's image without the consent from MS Commercial, Cayman, the firm that owns Salah's image rights.
