The latest transfer rumours involving Chelsea see Jose Mourinho's team linked with a pair of defensive midfielders, as well as a roving forward from the Bundesliga.
Mourinho has already strengthened his squad's creative potential significantly with the addition of ex-Arsenal and FC Barcelona schemer Cesc Fabregas. Speaking of the Gunners, Chelsea are reportedly considering a swoop for another former Arsenal midfield gem.
Here's the latest news, beginning with an old face.
Alex Song, FC Barcelona
While Arsenal boss Arsene Wenger stockpiles attacking midfielders as if he expects the position to be outlawed soon, Mourinho rarely sees a defensive midfielder he doesn't like.
Despite the presence of players such as Ramires, Nemanja Matic and Jon Obi Mikel, Chelsea are reportedly keen on Alex Song. The former Arsenal bruiser and current Barca flop is available for £20 million, per Alex Harris of The Daily Express.
That's a hefty fee for a player whose career has hit the skids since he left north London for Catalonia in 2012. Marca reporter Luis F. Rojo has detailed Song's struggles at Barcelona:
If they manage to sell him for that money, it will have proven to be a great deal for the club as they bought the player off Arsenal for €19m. It would be quite a surprise, too, as the player has not exactly shined since his arrival. He played very little with Tito Vilanova and even less so with Gerardo Martino. He has filled in for Sergio Busquets every now and again, but his performances have been far below those of the Spain international.
As stated, it's not as if Chelsea have a glaring need at the position. Of course, that could change if Real Madrid get serious about making a move for Ramires.
Los Blancos chief Carlo Ancelotti is apparently enamoured with the energetic Brazilian powerhouse, per Daily Star writer Nick Lustig. However, even if Ramires turns his back on Stamford Bridge, Song may not be a competent replacement.
Yes he knows the Premier League and isn't afraid to use his physicality, but the Cameroon international is suspect positionally and blighted by inconsistent effort.
During his final season at Arsenal, Song proved himself more adept going forward than shielding a back four. Mourinho might be best served looking to one of his former players instead.
Sami Khedira, Real Madrid
If Song's effort can be questioned, nobody can dispute Sami Khedira's willingness to cover every blade of grass. A classic midfield engine, Khedira played for Mourinho at Real Madrid, and he is on his former manager's radar, per Daily Star writer Rhys Turrell.
The reporter claims Arsenal manager Wenger is also interested but states that Chelsea have the advantage in any potential deal:
The Gunners boss has been handed £100m to transform the north Londoners into genuine title contenders after their challenge for top spot fell away last season.
He's identified Khedira as someone who could add bite to a midfield sorely lacking a top-class defensive figurehead, but Arsenal now look set to miss out, with their London rivals in pole position to seal a deal.
Mourinho knows all about Khedira's ability at both ends of the pitch: He is physically imposing in the tackle and possesses a keen eye for goal.
With Fabregas now in the ranks, it would be a good idea to complement his languid, probing style with some real energy. Khedira makes perfect sense if Ramires leaves.
Pierre-Emerick Aubameyang, Borussia Dortmund
Mourinho is apparently prepared to divert himself from becoming even more defensive long enough to strengthen Chelsea's options in attack. One of his primary targets is Borussia Dortmund forward Pierre-Emerick Aubameyang, according to Alex Harris of The Daily Express.
Like Song, Aubameyang has endured his share of struggles since switching clubs. The former AS Saint-Etienne ace found his first experience of the Bundesliga a tough one.
Despite supposed issues with his transition, Dortmund don't appear ready to part ways just yet. Harris states that the club's CEO Hans-Joachim Watzke, refuted Chelsea's initial interest back in May:
Why should he be leaving? He has just played here for one season.
We did not believe he would be put up [in the team] from the start in every match for our club.
We have an immense competition for places in the first team, this was impossible for him.
We are content with Aubameyang, he has a contract left at our club.
While that's not the strongest endorsement of the player, it doesn't exactly sound like he is about to be shoved through the exit door either. However, Harris believes Dortmund's recent capture of ex-Torino striker Ciro Immobile could change things.
Aubameyang is an interesting target for Chelsea. He possesses blistering pace, which he often unleashes from wide areas.
Yet Chelsea's current squad is well stocked with fliers from the flanks; Andre Schurrle, Willian, Eden Hazard and Mohamed Salah give the Blues ample pace up front.
They are also each more competent in front of goal than the 24-year-old Aubameyang, who can be erratic once he latches onto a chance.
However, that's the kind of bad habit that can be coached out of him. There's no denying Aubameyang's movement is clever, quick and thoughtful.
That makes him an ideal target for Fabregas, who loves to thread passes between the lines to connect with pacey runners.
Chelsea's latest transfer rumours show Mourinho is casting a wide net. They also prove his commitment to overhauling a team that couldn't win a trophy last season.
