Contrast Frans attitude with that of Liam Craig. Fran didn't even have an official move lined up like Liams pre-contract. In fact Muzz still throws himself about and he's leaving too.
Sandaza is the very definition of a mercenary. If the Jambos had any £££ left he'd be heading there next. With a bit more sense he would have knuckled down and got a better move than even Ibrox could have offered.
