The 18-year-old midfielder currently plays for Neftchi Baku in his domestic league, but recently underwent a medical on Merseyside. The deal means the Toffees will be able to sign Abdullayev any time during the next two years, subject to a work permit being granted.

Abdullayev, who is Azerbaijan's youngest international having made his debut at the age of just 16, is best known for his solo strike against Scotland Under-21s in March.
