Sculli has arrived in the port city this afternoon to undergo his medical after the two clubs agreed a deal for the 30-year-old.
"I'm emotional," he said. "I left on January 18 last year. I return on January 18, 12 months later. When I left here I never thought that I would be able to return one day.
"This is a challenge for me and I'll have to work hard and well to win the faith of the Coach."
