Celtic fans are desperate for the Portuguese star to join the club on a permanent deal after he impressed during his loan spell.
He 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.
The deadline day arrival has bought into Celtic's approach of being relentless with the ball and without it, and the fans have every right to be excited for what is to come.
The transfer window will open on June 10 and close on September 1 in Scotland.
