Chelsea have endured quite a summer so far, with the Blues sending out their usual quota of youngsters as well as releasing some former stars.
The likes of Florent Malouda and Yossi Benayoun have both left, although Hilario, who was originally released, has rejoined the club on a 12-month contract.
New signings Andre Schuerrle and Marco van Ginkel have quickly settled into the team on the team's tour of the USA and Asia, and now Jose Mourinho has less than a month to decide whether he wants to add to his squad.
That said, his players may be in high demand. We take a look at which Chelsea stars could be heading out of Stamford Bridge, as well as potential arrivals coming in.

-- UPDATED 6TH AUGUST --
As the Wayne Rooney transfer saga rumbles on, it's fair to say that readers aren't the only ones frustrated by the continued speculation over the England striker's future.
Chelsea are continuing to pursue the 27-year-old as the former Everton forward looks to leave Old Trafford this summer, and had a second bid believed to be in the region of £30 million rejected by the Premier League champions, per BBC Sport.
You don't look too angry there, Wayne...
You're a professional footballer. What do you do when a club signs a newer, younger version of you? Leave, of course.
The former Liverpool playmaker has been linked with a return to Anfield as a result, with his contract close to expiring, while his former coach Jose Mourinho—now at Chelsea—has been credited with an interest, per The Metro.
With new coach Carlo Ancelotti coming in and his assistant Zinedine Zidane, Alonso spoke of his excitement about working with the Frenchman, adding he is "very motivated about working alongside him because of everything he has achieved and experienced."
With Alonso suggesting that his intention is to stay at the Santiago Bernabeu, it appears that Mourinho may need to look elsewhere if he wants to add another midfielder to the squad.
Jose Mourinho wants Wayne Rooney at Chelsea, we all know that. And usually, what the Special One wants, he gets without any hitches.
But this time, it's not a simple process.
Manchester United are providing some heavy resistance to Chelsea's attempts to bring Rooney to Stamford Bridge, having missed out on him nine years ago.
The Blues have already had a first offer of £23 million plus add-ons rejected, and more recently, an improved bid of £30 million was immediately turned down by their Premier League rivals, per The Daily Mail.
The same article claims Rooney will force a move to the West London club by handing in an official transfer request, which is likely to be dismissed by David Moyes.
As well as possible arrivals, Jose Mourinho must be wary of other clubs circulating for his own players.
Both Bayern Munich and Barcelona have shown an interest in signing the Blues' central defender, David Luiz, per ESPN, who helped Brazil to winning the Confederations Cup earlier this summer.
And while Pep Guardiola ruled out bringing the 26-year-old to the Allianz Arena, Barcelona have made Luiz one of their top targets this summer, with the Catalan club preparing a bid for the highly-rated centre-back, according to The Mirror.
But Mourinho has been defiant in his message to his former foes in Spain, saying Luiz is not for sale and is a key part of his plans, per Goal.com.
With the former Benfica defender seemingly happy to stay in London, and a huge fee to force Chelsea into negotiations, it seems he's unlikely to leave this season.
