Willian is frustrated by Chelsea's delays over new contract talks.

The midfielder, reports UOL Esporte, is also upset being blocked from moving to PSG last week.

Willian is keen to extend his stay with Chelsea, but their policy of offering only 12-month deals to players of 30 years of age and older has upset the midfielder.

The Brazil international, 30, wants a longer contract - something which Chelsea are refusing to discuss.

This is in contrast to PSG, which were happy to offer extended terms to the player's camp last week. However, the deal never took off with Chelsea refusing to do business.
