Celtic fans are desperate for the Portuguese star to join the club on a permanent deal after such an impressive loan spell.
The winger has shown he has an eye for goal and his pace, skill and movement has been a real handful for defences to deal with.
If you score 13 goals and make 14 assists in your first season at a new club, you will give supporters hope that there is more to come once Jota has a full pre-season under him.
The fans have every right to be excited for what is to come, as the deadline day arrival has bought into the Celtic approach of being relentless with the ball and without it.
When the transfer window opens on June 10 and closes at midnight on September 1 in Scotland, who will be moving?
