The Blues are on a look-out for a new forward this summer, with Timo Werner's current tally of five Premier League goals proving inadequate for a side looking to mount a serious challenge for the title next season.
Manchester City's Sergio Aguero is rumoured to now be a key target for the west London outfit, following the news that he's going to leave the Etihad Stadium for a new challenge at the end of the current campaign.
What's the story?
The Daily Mail report that Chelsea are "leading the race" to sign the 32-year-old, as he apparently wishes to continue playing his football in the Premier League.
It is suggested that Aguero would be unwilling to tarnish his relationship with City fans by moving to local rivals Manchester United, while Liverpool look likely to plough the majority of their transfer budget into signing a new centre-back.
Chelsea are credited with being one of a handful of teams capable of paying the striker's wages, which are thought to be in the region of £13m-per-year.
Eintracht Frankfurt’s Andre Silva and Lautaro Martinez of Inter are also listed as potential targets for the Blues.
Do the bookies fancy it?
Currently, they've got Chelsea down as second favourites to sign Aguero but at a fairly distant 6/1.
Barcelona are still the odds-on favourites to land the Argentina international, while Arsenal, Atletico Madrid and the rather vague 'any Argentinian club' are also in the mix at 8/1.
How likely are Chelsea to seal the deal?
The Blues have also been heavily-linked with Erling Haaland, but he could well opt to join either Real Madrid or Barcelona, following meetings held by his agent in Spain yesterday - for now, then a move for the Borussia Dortmund star looks a long way off.
These days, managers at the top level have little choice over the players they sign, and this is very much the case at Chelsea, with the likes of advisers Petr Cech and Piet de Visser, and director Marina Granovskaia making the big decisions when it comes to recruitment.
In other words, it's not going to be Thomas Tuchel's decision.
Roman Abramovich, much like Indiana Jones, has a real penchant for hoovering up historical artefacts - Andriy Shevchenko, Radamel Falcao, Gonzalo Higuain, Samuel Eto'o et al - and Aguero could well be the next exhibit in Chelsea's museum of footballing relics.
That is, however, perhaps a tad harsh - while he may be in the twilight of his footballing career, the ex-Atletico Madrid star has only failed to score less than twenty goals in a season just once during his ten-year stint with the Citizens, and is a proven, lethal finisher in the English top tier.
