Benfica winger Jota has agreed a four-year deal to join Celtic on a permanent basis.
Celtic had been waiting for the player to arrive back from holiday to finalise personal terms and Jota was at Celtic Park on Thursday night to commit his future to the Scottish champions.
The 23-year-old had previously told Benfica he wished to remain at Celtic after initially joining on loan in the summer.
Jota played a key part in Celtic's double-winning side - contributing to 27 goals across all competitions as Ange Postecoglou's side won the league and League Cup.
The Hoops triggered the £6.3m option-to-buy clause and agreed terms with Benfica last month. Benfica will retain 30 per cent of any future transfer fee generated should Celtic decide to sell Jota.
