The 27-year-old defensive midfielder currently plays for Qatar SC.
Qatar SC has recently signed ex-Persepolis midfielder Bashar Resan and Karimi will most likely leave the team to join Al-Duhail football team on loan.
The iconic midfielder had been linked with a return to Iranian club Esteghlal.
Al-Duhail sports officer Faraj Saleh al-Marri has confirmed negotiations with Karimi.
