Chelsea have jumped into the race for Celta Vigo midfielder Stanislav Lobotka.
The attacker is prepared to leave this month and PSG have been linked with him. While his agent has publicly encouraged Napoli to move for him in January.
However, Calciomercato.it says Chelsea are now keen as they seek to add a midfield signing to Maurizio Sarri's squad.
Chelsea have turned to Lobotka after being frustrated in negotiations with Zenit St Petersburg for Leandro Paredes.
