According to sporx.com, the proposal for the Brazilian is in the region of €2.5m.

Including Cetin as part of a dual deal could enable them to lower the price-tag, but they face competition from Galatasaray.

Cetin is a 23-year-old Turkey international centre-back who cost €3m to sign from Genclerbirligi last summer.

He struggled to make an impact and made just five Serie A appearances.
