His involvement in the final with Chelsea has been in doubt because of political tension between his native Armenia and the host nation.
Armenia and Azerbaijan have been in conflict over issues in the disputed Nagorno-Karabakh region for three decades.

Abdullayeva said: "Many major sports events have been hosted in Azerbaijan, and Armenian athletes have taken part in them. Sports and politics are separate."
