Al-Ittihad have verbally agreed a €60million (£50.5million) package including add-ons with Aston Villa for Moussa Diaby.
As reported by Fabrizio Romano, the winger has agreed a five-year deal with the Saudi Arabian side.
The deal is very close to being finalised, with Diaby set to leave Villa after just one year at the club.
Al-Ittihad are also targeting Ederson and have contacted Manchester City about the goalkeeper.
City, who value Ederson at around £50million, have already rejected an offer of £25million from Al-Nassr.
