Celtic is also targeting Mohammadi as a potential replacement for Kieran Tierney, who has caught the eye of Arsenal.
Mohammadi, who has been capped 30 times for Iran, represented Team Melli in the 2018 World Cup.
The Iranian winger can also play anywhere down the left flank.
The 25-year-old is a player in demand as he is available on a free transfer after ending his spell at Russian club Akhmat Grozy, where his deal expires at the end of this month.
