Petr Cech would not be drawn on his future on transfer deadline day after falling out of Chelsea's first XI for the first time in a decade.
The 32-year-old sees "no reason to panic, pack up and leave" Stamford Bridge, but would "not exclude anything" after beginning the 2014-15 season on the substitutes' bench.
He also wrote on Twitter that the transfer window "will be interesting till the last minute".
Thibaut Courtois has been selected in goal by manager Jose Mourinho in a situation reminiscent of when Cech was installed as number one ahead of the established Carlo Cudicini after his signing from Rennes in June 2004.
Speaking in Prague while on national team duty with the Czech Republic ahead of Wednesday's friendly with the United States, he told sport.cz: "I've been at the club for 10 years, the situation is now new to me.
The 10 biggest transfers that could still happen
The 10 biggest transfers that could still happen
1/10 Radamel Falcao - Manchester United
Despite missing more than six months with injury, the Colombian striker remains one of the hottest properties in Europe. Falcao had been linked with a move to Real Madrid, but Arsenal and Manchester City had been linked with a move on deadline day for the striker. Enter Manchester United, who pulled off the shock of the summer after a season-long loan was agreed in principle with a view to a permanent deal.
2/10 Sami Khedira - Arsenal/Chelsea
Will he, won’t he, will he, won’t he? Sami Khedira is clearly surplus to requirements at Real Madrid after the arrival of Toni Kroos but his wage demands and fee seem to be getting in the way of a resolution. He is a fantastic player and would be a major coup if he were to arrive at either London club, but this transfer will probably rumble on until deadline day
3/10 Edinson Cavani - Liverpool
Another striker unhappy in Ligue 1, Cavani scored 25 goals for PSG last season but is reported to be unhappy playing second fiddle to Zlatan Ibrahimovic in Paris. PSG don’t want to sell, but Brendan Rodgers is looking at the top end of the market to replace Luis Suarez and could spend big on Cavani or Falcao
4/10 Mehdi Benatia - Manchester United
The classy Moroccan centre-back would perfectly fit the profile as one of the back three in Louis van Gaal's system. The Roma man, believed to be available for about £30m, is very good on the ball, an excellent athlete and a fierce competitor. He is comfortable taking the ball forward and is a threat at set-pieces
5/10 Arturo Vidal - Mancester United
This potential transfer seems to have been rumbling on all summer but appears unlikely. Vidal is supposedly keen on a move and a midfielder of Vidal’s quality would be an upgrade over United’s current crop, but Louis van Gaal is believed to have doubts about the Chilean’s knee
6/10 Petr Cech - Real Madrid/PSG
Jose Mourinho wants Cech to stay in west London but the giant goalkeeper is too good to waste his away on the Chelsea bench. Real Madrid, Monaco and Paris Saint-Germain seem the likeliest destinations for the 32-year-old, who is still one of the very, very best in the world
7/10 Mats Hummels - Manchester United
Again, this deal appeared to be dead after Jurgen Klopp said he had no intention to sell and made the World Cup hero his club captain. But rumours for the German centre-back continue to swirl and given United’s defensive woes – Tyler Blackett is not the answer – a huge bid could tempt the Bundesliga side
8/10 Marco Reus - Various
One of the world’s best young players, Reus is being linked with just about every major European club. Manchester United and Liverpool appear to be leading the race in England, but Bayern Munich, Real Madrid and several other clubs would be delighted with the youngster. Reus’ cheap release clause, the cause of all the speculation, doesn’t take effect until next summer, so a big bid may tempt Dortmund to sell now
9/10 Victor Valdes - Liverpool
The former Barcelona goalkeeper is looking for a new club as he continues his recovery from a serious knee injury that forced him out of the World Cup. Liverpool are looking for a new goalkeeper after letting go of Pepe Reina, and Valdes would certainly provide competition for No 1 Simon Mignolet should he regain full fitness.
10/10 Danny Welbeck - Arsenal/Tottenham
The England international is a target for a number of Premier League clubs, but Manchester United are reluctant to strengthen a potential top-four rival with his departure. As a result, any destination will have to cough up a £5m just to take him on loan, while a permanent deal could be largely inflated given his homegrown status.
"The three opening matches I could not play for the team. I have no reason to panic, pack up and leave.
"I am a Chelsea player, where I have two more years of contract.
"In football, nothing can be predicted in advance, nothing is ever perfect.
"A lot of players go on representative duty, yet still many transfer clubs.
"The offer would have to be right for everyone. I do not exclude anything (or) know the answer."
Ashley Cole and Frank Lampard - two other mainstays of the Chelsea side Cech has been part of for 10 years - left the club during the summer, showing Mourinho has little room for sentiment on his second spell as Blues boss.
Transfer latest: Van Ginkel follows Torres to AC Milan
United secure shock Falcao loan
Hernandez heads to Real after Falcao arrival
David Luiz, Romelu Lukaku, Demba Ba and Samuel Eto'o have also departed, with Loic Remy almost certainly Chelsea's final addition of the transfer window.
Mourinho had long stated that the window was closed for the Blues, having completed deals for Diego Costa, Cesc Fabregas, Filipe Luis and the returning Didier Drogba earlier in the summer.

Fernando Torres' departure to AC Milan for the final two years of his five-and-a-half-year Chelsea contract - in effect ending his time at Stamford Bridge following his £50million move from Liverpool in January 2011 - necessitated the arrival of another striker, but even then Mourinho moved swiftly to sign Remy from QPR for a reported fee of £10.5million.
It could be if an opportunity arises - like the one last year which saw Willian join despite passing a medical at Tottenham - Chelsea may make a further signing, but, for now, Remy completes the squad for the first half of the 2014-15 campaign.
Many of those not in contention for a first-team place have left on loan - 21 in all after Marco van Ginkel, the midfielder who spent most of last season out with a serious knee injury, joined Torres at the San Siro.
The Dutchman's departure means Chelsea fulfil the Premier League's homegrown player rule and will have the maximum 17 foreign players in their 25-man squad.
Of the loan group, only Patrick Bamford, whose initial loan runs until January, did not leave on a season-long deal.
Cech later took to Twitter with a message which suggested he will be either an interested observer in the final hours of transfer deadline day, or that he could be on the move.
Cech wrote on Twitter: "Have a lovely day / night and enjoy the last hours of the transfer window football fans ... It will be interesting till the last minute."
A 22nd Chelsea player left on loan when Nathaniel Chalobah joined Burnley on loan until January.
"The move gives the 19-year-old his first opportunity to gain top-flight first-team experience," the announcement on chelseafc.com read.
Chelsea beat Burnley 3-1 in their opening match of the Premier League season.
