Zenit St Petersburg are demanding Chelsea go higher if they want to sign Leandro Paredes.
The Daily Mail says Zenit want £36m for Chelsea target Leandro Paredes.
Talks between the clubs opened last week though Chelsea fell short with their opening offer for the Argentine midfielder who returned for training on Monday after the Russian League winter break.
Chelsea's opening offer was £26.8million, as they look to replace Monaco signing Cesc Fabregas.
Paredes has scored seven times in his 43 matches for Zenit St Petersburg. He's also previously played for Empoli on loan, Roma, Chievo, and Boca Juniors.
