With Yury Zhirkov set to be sold to Anzhi, Uruguay international Pereira is under consideration as a direct replacement at Chelsea, says O Jogo.

Pereira helped Uruguay win the Copa America this summer and remains on holiday.

The defender has also been linked with Liverpool and carries a buyout clause of €30 million.
