A multi-million-pound option-to-buy was inserted in the 22-year-old’s season-long deal giving Ange Postecoglou the possibility to keep him longer if the temporary transfer was successful.
The Portuguese has caught the eye since arriving at the end of the transfer window and forced £3.5m wide man Liel Abada onto the fringes. Now, despite a hamstring injury putting him on the sidelines until next year, the Hoops are said to be ready to deal Jota in.
Sky Sports report the club will pay the set fee before the end of the season and keep the winger at Parkhead beyond his loan spell.
Jota has scored five times in 11 games this term. He could be joined by a trio of Japanese players, following the same path as Postecoglou and Kyogo Furuhashi made in the summer from the J-League to the east end of Glasgow.
