Cech is widely expected to bring an end to his 11-year stay at Stamford Bridge and move to London rivals Arsenal, having seen his first-team opportunities at Chelsea limited due to the presence of Thibaut Courtois.
However, after reports indicated an announcement was imminent, Cech took the unusual step of sharing a message posted by his management company - The Sports PR Company - on Twitter.
The message retweeted by Cech read: "...as we told you, No transfer deal has been done yet for @PetrCech - as soon as [there is] any news @PetrCech will confirm."
Earlier on Monday, John Terry suggested Arsenal would benefit greatly should they manage to capture the vastly experienced Cech, a winner of four Premier League titles, four FA Cups and the 2012 UEFA Champions League during his time with Chelsea.
Chelsea captain Terry told talkSPORT: "There's talk of Arsenal signing Petr Cech and, if they do get him, he will strengthen them for sure. He will save them 12 or 15 points a season."
