Although Jose Mourinho's men are one positive result away from reaching the Champions League final, the Portuguese boss will be hoping to improve his squad with a number of summer dealings.
Paris Saint-Germain's Ezequiel Lavezzi and Adrien Rabiot are the latest to be linked with a move to Stamford Bridge, while Frank Lampard is touted to stay. Here, we detail the latest news on each.
Latest on Chelsea's Potential Summer Transfer Dealings
Ezequiel Lavezzi, Paris Saint-Germain
Mourinho's reported interest in Lavezzi may have been sparked by the Argentinian's performance during PSG's recent Champions League showdown with Chelsea. Although quiet in the second leg, Lavezzi's excellent opening goal gave the French club an early advantage during the first tie.
Simon Jones of the Mail Online believes Lavezzi is the latest name to join Mourinho's attacking targets:
Chelsea are keen to speak to Paris St Germain about Ezequiel Lavezzi. The 28-year-old Argentine's representatives were in London early this month as they gauged interest for their client and Chelsea want two forwards for their summer rebuilding.
Lavezzi is a powerful, pacey forward whose natural eye for goal makes him an attractive prospect. The versatile 28-year-old has scored nine in 38 games across Ligue 1 and Europe this season, per WhoScored.com, but he could be the subject of a transfer tug of war, as noted by Jonathan Johnson of ESPN FC:
An older option to the likes of Eden Hazard, Andre Schurrle, Mohamed Salah and Willian, it is difficult to see Lavezzi fitting in without halting the progress of another Chelsea star.
Adrien Rabiot, Paris Saint-Germain
Staying in the Parc des Princes, Mourinho is also reported to be eyeing a deal for Rabiot, the impressive 19-year-old midfielder, as reported by Michael Butler of The Guardian:
Jose Mourinho has taken a particular shine to the shaggy-haired youngster and with his contract expiring in 2015, has decided that £8m is enough to prise him from Paris and beat both Juventus and Arsenal to his signature.
It seems a good deal of Rabiot's potential transfer could revolve around his pay demands. Currently earning £5,000 per week and heading toward the end of his contract, Chelsea will feel they can land the versatile player without having to pay top dollar.
Which player do Chelsea need most?
PSG boss Laurent Blanc hopes Rabiot will stay, but he acknowledges the starlet's wishes could see him poached, as reported by Sky Sports.
"I can understand he is impatient," said Blanc. "But he must not forget he belongs to a very big club and you have to be patient in life. I hope he will stay at the club."
Rabiot has made 29 appearances across the domestic division and Champions League, as recorded by WhoScored.com. He is an imaginative passer of the ball, excellent with possession at his feet and boasts real confidence for a player who competes in a squad jam-packed with quality.
He can expect the same battle if he eventually joins Chelsea, albeit on a heftier wage.
Although Lampard's on-pitch influence in west London is waning, the veteran midfielder is set to net a one-year contract extension worth "close" to the £125,000 per week he is currently paid, per Tony Banks of The Express:
"The 35 year old, whose current deal runs out at the end of June, has been in talks with the club over extending his contract for weeks but agreement on the new contract is now close," reads the article.
Lampard has made 35 appearances across the Premier League and Europe, scoring seven goals and providing five assists. Although he is no longer a guaranteed starter, the former West Ham midfielder has showed enough to maintain his position amongst the Chelsea furniture.
He is a leading figure in a squad that is getting younger, and alongside John Terry, looks set to oversee Chelsea's transitional period before calling time on his career. Like Ryan Giggs at Manchester United, Lampard's presence is arguably as important as his performances these days, as Chelsea retain a symbol of past success to inspire the team's developing talents.
Mourinho has drilled his side into a hard-working, energetic outfit since returning to Stamford Bridge. He'll be hoping to sharpen his forward line's attack with the acquisition of Lavezzi or someone of similar quality, while capturing Rabiot on a cut-price deal is certainly plausible in this era of UEFA's financial fair play rules.
Lampard's retention is also a necessary step toward building a winning team, as Mourinho is sure to mix the old with the new during a summer of alterations.
