The agent of Porto left-back Alvaro Pereira cannot rule out a January move to Chelsea.

Pereira penned a new deal earlier this season, but remains a target for Chelsea.

"I have read the news about Chelsea's interest, but I am not going to say anything about it at the moment," Alejandro Savich told Maisfutebol.

"Alvaro Pereira recently renewed his contract until 2016, so he has a contract with Porto, but there is a release clause.

"We are going to have to wait a little bit, we will see what could happen in the future."
