Hammersmith and Fulham Council says it can't comment further on Chelsea's plans to regenerate its famous Stamford Bridge stadium, despite suggestions it is in favour of the proposal.
BBC Sport reported on Tuesday that the council considered the club's plans for a revamped 60,000 capacity stadium were "generally acceptable".
A spokesman for the council said: "Chelsea have not submitted anything to the council. It's impossible for the council to comment when there is nothing to comment on."
A full planning application has long been anticipated and is expected to be submitted in due course, whereby it will go before councillors for debate.
Earlier this month, the club set out its vision for a new-look Stamford Bridge, where they club has played since 1905.
It was last redeveloped in the 1990s, bringing it up to some 42,000 capacity. However, this pales in comparison to the club's major rivals.
Premier League giants Manchester United's Old Trafford stadium holds 76,000, Arsenal's Emirates stadium 60,000 and Manchester City's Etihad stadium 55,000.
The development will include a club shop, kiosks and museums, as well as restaurants and cafes.
Plans include providing a structure to form platforms over sections of the District Line adjacent to Fulham Broadway Station.
They also aim to provide an enlarged concourse area with new pedestrian access from Fulham Road, additional car parking, landscaping and other related works.
Its futuristic design was hailed by fans and readers of getwestlondon when they were unveiled just a few weeks ago.
The club is thought to be close to sealing an agreement with Wembley to host their home matches during the redevelopment of Stamford Bridge.
Chelsea bosses had previously explored the possibility of relocating temporarily to Twickenham, the England rugby union stadium, which is gearing up to host the Rugby World Cup.
The council spokesman added the council could not comment on the source of the BBC's report.
