While Colomba confirmed that Giovinco would remain, he also made it clear that he'd like the Brazilian-born Italian international too.
"Giovinco has great qualities, but he still has a lot of work to do," Colomba told Radio Sportiva on Monday. "The club will buy a half share in him though.
"Amauri? He's a mature player. He'd be very useful for us next season and I really do hope that he remains."
