CSKA Moscow insist no agreement has been struck with Inter Milan over a deal for Daniel Carvalho.
"Lately there have been many ungrounded rumours and speculation about Carvalho leaving CKSA," read a statement on the club's website.
"CSKA can report that Carvalho's contract has been extended until the end of 2009 with an option for a further extension.
"We hope that this information will end talk not only of Carvalho's departure, but also of a so-called 'Brazilian problem' at CSKA, which has been invented by the media."
The deal seemed to have been done on Thursday when Nerazzurri director Ernesto Paolillo stressed his satisfaction at the swoop.
