The countdown is on... Who could be on the move?
Where else could we begin, Raheem Sterling?
The future of Raheem Sterling at Chelsea wasn't really in question until an hour before the Blues' first game on Sunday against Manchester City.
His exclusion from the team and subsequent statement from Sterling's representatives seeking "clarity" about his position at the club point to the possibility of his departure.
The former Liverpool forward, who is only 29, would undoubtedly be wanted? A possible move has already been mentioned in relation to Crystal Palace and West Ham.
Since signing for £50 million in July 2022 from Manchester City, he has played 81 games for Chelsea.
Joao Felix, Ben Chilwell, and Conor Gallagher could be busy at Chelsea. It's no surprise that Stamford Bridge shows signs of discontent.
This summer, Chelsea spent about £185 million on 11 new players, giving manager Enzo Maresca a team with more than 40 senior players.
You can't please everyone.
Even though Conor Gallagher's move to Atletico Madrid is still on hold, his departure from the Bridge is certain. Ben Chilwell, on the other hand, may be considering a move after being left out of Sunday's squad.
Trevoh Chalobah, a defender, and Noni Madueke, a midfielder, were two other Chelsea players who did not participate in the Premier League's inaugural weekend.
Be ready for a fire sale at Stamford Bridge in the coming days as Maresca tries to sell some of his team.
Romelu Lukaku, a striker, is another player who could leave Chelsea this month; he is still on the Blues' books.
The 31-year-old, who has been on loan in Italy for the past two years, is now wanted by Napoli. One possibility that is being heavily discussed is a swap deal for Victor Osimhen.
Atletico Madrid's Joao Felix is another potential Chelsea newcomer to keep an eye on. The Spanish club wants to include him in a deal for Gallagher.
Confused? Before the window closes, Chelsea seems to be going through a lot more ups and downs.
Thomas Frank, the manager of Brentford, wouldn't say that Ivan Toney had played his last game for the Bees, but it seems pretty likely.
After a £35 million offer to join Saudi side Al-Ahli was turned down last week, the 28-year-old was left out of Brentford's opener against Crystal Palace.
Frank added, "When Toney leaves, not if," when asked by BBC Radio 5 Live if it was a matter of when rather than if. Yes, I suppose that's just."
Toney has been with Brentford for four years. During the 2022-23 Premier League season, he scored 20 goals in 33 games.
He is out of contract this summer and has been linked to moves to Arsenal and Chelsea in the past; however, a move to Saudi Arabia appears to be the most likely option at this point.
Marc Guehi In two weeks, will Marc Guehi still be a Crystal Palace player? At this point, no one knows.
The England defender has been the subject of three Newcastle bids, the most recent of which was for approximately £60 million.
The center back captained Palace in their Sunday defeat by Brentford, but Newcastle's willingness to increase their offer is unknown.
With this one, we'll have to see.
Joe Gomez Liverpool's Joe Gomez is being touted as an alternative in the event that Newcastle give up on their pursuit of Guehi.
The defender is now heavily linked with a move away from Anfield after being left out of Arne Slot's first Premier League squad on Saturday.
As a possible Guehi replacement, Crystal Palace, Fulham, Aston Villa, and Newcastle are reportedly interested in the 27-year-old.
Mikel Merino It seems like it will only get worse with time.
Merino, a Spain midfielder, is the subject of negotiations between Arsenal and Real Sociedad.
He played in all seven matches for the Spanish team that won Euro 2024 and scored a late winner against Germany in their quarterfinal match.
Since the 28-year-old has less than a year left on his contract, he could talk to clubs about signing on a free transfer in January, which could help Arsenal close the deal.
Jarrad Branthwaite Everton want to keep their 22-year-old center back, but there is a lot of "transfer noise."
Earlier this summer, Manchester United made two bids for Jarrad Branthwaite, which the Toffees rejected. Since then, Manchester United has signed Matthijs de Ligt from Bayern Munich.
However, there are a lot of other teams that are reportedly ready to move, with Liverpool, their city rival, being the most recent link.
Scott McTominay and Jadon Sancho Manchester United may see two notable departures this summer.
After a disagreement with manager Eric ten Hag last season and a subsequent loan move to Borussia Dortmund, Jadon Sancho may be back at Manchester United, but for how long?
Sancho didn't play in Friday's first game against Fulham, so he may be wondering how many chances he will get with so many injured players still out.
After being left out of United's starting lineup in their win over Fulham, Scott McTominay is another player who has been linked to leaving the club.
There are a few clubs that have been reported to be interested, including Brighton, Crystal Palace, and the Cottagers.
