The Sicilians say the asking price demanded by Nacional is too rich for them.
"Rolin is an important player and a Uruguay international who many much bigger clubs have set their sights on," explained general manager Sergio Gasparin.
"We do not deny he is a player of great quality, but he is out of our economic reach. It's very difficult that a player with this price-tag can reach a side like Catania.
"We are looking for a centre-back and someone will be leaving from the attack, definitely one out of Mirco Antenucci and Taka Morimoto."
