Atalanta are set to activate their €15m purchase option for Chelsea-owned midfielder Mario Pasalic.
He has been on loan for two seasons in Bergamo and done enough to secure a permanent transfer to the Serie A surprise outfit.
Multiple sources are confident the club will use its option to buy for €15m, in addition to the €2.5m paid for the two-year loan deal.
Although Chelsea purchased Pasalic from Hajduk Split for €2.5m in 2014, he never made a single competitive appearance for the club.
There were loan spells at Elche in Spain, Monaco in France, Milan in Italy and Spartak Moscow in Russia.
So far this season, Pasalic has made 32 appearances for Atalanta, scoring seven goals and providing seven assists.
