Jota spent last season on a loan from Benfica and has decided to join Celtic for the next five years.
When he moved to Glasgow, the fee had been agreed.
In 40 appearances, the Portuguese scored 13 goals and provided 14 assists for the Australian team.
With the season that we had, I think it was great for everyone.
I had a great time. People only know how big Celtic is once they are inside the club and inside the structure.
I fell in love with the club because I got to know it in a different way. It's a good time to be here and I want to progress.
Jota was capped up to under-21 level by his country after playing for Real Valladolid.

I joined Celtic to give joy to the fans, to our team and to conquer as many things as possible.
