Campbell has been loaned out six times since arriving at the Gunners from Saprissa in 2011.
The Costa Rican forward has had spells at Olympiacos, Villarreal and Sporting, with his game for Arsenal coming in 2015.
He struggled to nail down a place in the side under Arsene Wenger but with Emery taking over this summer there may be some hope for the 26-year-old.
Campbell has one year remaining on his Arsenal contract but he admits he is still in the dark over his future with the club.
“This weekend, I’m traveling and they’ll decide what’s coming next,” he told La Nacion.
“I know that I have a lot left to show in football, so wherever it may be I’ll do things as well as possible to enjoy this sport.”
Campbell struggled with injuries last season while on loan at Real Betis.
The striker managed just nine appearances but insists he has still learned from the experience.
“It was a tough season because of the injury,” Campbell added.
“At the end I grew more as a person because I already had been through the good and the bad of football.
“Now with this you can be a better person in the face of the future.”
