Danilo Pantic will spend the rest of the season on loan in Hungary.
The 22-year-old Serbian midfielder has been on loan back in his home country for the past two seasons where he was a regular in the Partizan Belgrade side and won the Serbian Cup. He will now play for MOL Fehervar.
Pantic signed for Chelsea in the summer of 2015, before spending two seasons on loan in the Dutch Eredivisie. Last summer he signed a new contract until 2021.
MOL Fehervar are better known to Chelsea fans as MOL Vidi, the club we played in the group stage of the Europa League last season. They have since changed their name for sponsorship reasons.
