Fenerbahce have set their price for Attila Szalai.
The Hungary defender is interesting Chelsea ahead of the January market.
Fanatik says Fener are aware of Chelsea's interest and prepared to sell the youngster for €20m.
The 23 year-old only moved to Fener last season and has established himself as a key player for Vitor Pereira's team.
His form for club and country has brought him to the attention of Chelsea scouts, which are now making enquiries about his availability.
