Chelsea on Monday were seeking an explanation from Spanish forward Fernando Torres regarding an interview in which he appeared to criticise his teammates.
The official website of Spain's Primera Liga last week interviewed Torres and the article later appeared in English translation on his website, including a comment that Chelsea's older players were "very slow" while in contrast praising the signing of compatriot Juan Mata.
Coach Andre Villas-Boas has asked the out-of-form striker for an explanation, although Torres is understood to have claimed what he said was not accurately translated on his website.
Chelsea are hoping to unearth the original with Villas-Boas saying: "We are going in-depth to regain the tape of that interview. "We'll see if things play exactly as they are in that interview."
The interview was authorised by Chelsea, otherwise Torres would have been facing a fine.
Villas-Boas said if the comments as transcribed in English proved to be an accurate rendition he would seek out Torres but stressed "we'd just talk. Just talk. To share opinion. If it (the interview) was unauthorised, I'd fine him. Of course."
Torres has struggled badly at Stamford Bridge since his move from Liverpool last January.
