As summer approaches, so the speculation intensifies.
After a season of discontent with their strikers, it's clear Chelsea require fresh faces in attack to help bolster their options next year.
Top of their shopping list appears to be Radamel Falcao and Diego Costa.
The Guardian recently reported Chelsea boss Jose Mourinho remains keen on Monaco's Falcao despite his knee injury, while rumors of his affection for Diego Costa also refuse to go away, per The Mirror.
Who would be the best fit at Chelsea?
In the Champions League on Tuesday night, however, Chelsea come up against a striker who has enough in his repertoire to turn Mourinho's head—Edinson Cavani.
The Uruguayan only joined Paris Saint-Germain last summer after the Ligue 1 side beat a host of European giants to his signature, paying Napoli £55 million.
Despite that, an apparent aversion to Laurent Blanc's tactics has resulted in reports Cavani has grown unsettled with life in the French capital.
ESPN reported only in January the striker could very well be looking for a new home come summer.
With Zlatan Ibrahimovic injured, Cavani will be centre stage at Stamford Bridge this week. A vintage performance to eliminate Chelsea from the Champions League could well be enough to convince Mourinho he should rethink his transfer plans.
By his own standards, it's been a rather quiet debut season for Cavani in France, with just the 22 goals. We say just, as he bagged 38 for Napoli last year on the back of scoring 33 in 2011-12.
It's statistics such as those that whet the appetite for how deadly he could prove to be in west London.
Alongside Eden Hazard, Oscar and either Willian, Andre Schurrle or recent addition Mohamed Salah, the 27-year-old would be provided enough ammunition to punish teams in the way Mourinho has craved his strikers would this term.
Indeed, it would prove the ideal move for Cavani, putting him back in the position where he has made his name in European football.
Hazard and Oscar would maintain their influence in Mourinho's thinking, yet a striker of Cavani's ability wouldn't go unnoticed in the way Samuel Eto'o, Fernando Torres and Demba Ba have this term.
At PSG, Cavani's price tag hasn't meant he has been the star attraction. In many ways, by moving to Parc des Princes, he has dared to upstage Zlatan, only it's back fired. As we've seen, there is only room for one star in attack and that's Ibrahimovic, with Cavani suffering as a result.
Featuring wide right as part of a front three, his influence hasn't quite been what PSG fans would have anticipated.
Cavani's goal return has been significant, but for £55 million, all of Europe would have expected more.
It's a mix of tactics and form that have played their part, although at Chelsea he would be given the opportunity to dismiss at least one of those problems.
And when it comes to form, he has shown these past few years he has the talent to cut it at the highest level.
Without an Ibrahimovic to prevent him playing in his favored central role, Cavani would flourish again. And with it, so too would Chelsea.
The Blues are in an enviable position right now. They may be outsiders to win either the Champions League or Premier League, but their season is still alive and has the potential to arrive at greatness, no matter how slim the prospect.
Had they a player of Cavani's ilk, the chances of that happening would be heightened significantly.
