Because Colak consistently finished his chances and Dessers consistently fucks up his chances. Would pick Colak over Dessers every day of the week
Not going to overexaggerate how good Colak was either but there was a feeling at the time he was here that, sure he won't create things out of nothing, but if a chance fell to him then it was going into the net. And not just tap ins or poaches either, some proper strikes and some nice plays like his second vs St Mirren in the 4-0 match etc.
