As Samuel Eto'o has been playing with Russian Premier League side Anzhi Makhachkala for the last two years, it's easy to forget just how good the Cameroon striker is.
At his peak he was arguably the best in the business.
With Barcelona he scored 129 goals in 201 games and was one third of a legendary attacking triumvirate, which also included Ronaldinho and Lionel Messi, at the Nou Camp.
The four-time African Player of the Year won the Pichichi during his spell in La Liga, picked up several league titles and won two Champions League winners' medals.
He made it a hat-trick of European Cup honours with Inter Milan in 2010, winning two more trophies in an historic year with the Italian giants, and has continued to score goals since 2011 after becoming the world's highest paid player at Anzhi.
With the Russian outfit in financial meltdown, Jose Mourinho - who coached Eto'o at the San Siro - looks set to capitalise, taking the prolific striker to Stamford Bridge in order to use him as his first-choice striker for the foreseeable future.
The Portuguese coach cited "mobility" as the reason for starting without a recognised striker against Manchester United at Old Trafford on Monday, but there have been suggestions that it was also a thinly-veiled message to Roman Abramovich that the team needs a new top-class striker in order to challenge for silverware.
It's abundantly clear that Mourinho does not fancy Demba Ba, who has been linked with a return to Newcastle United, while Fernando Torres has failed to impress at the start of the current season.
Romelu Lukaku, meanwhile, had been tipped to emerge as the club's first-choice striker this season - but it seems Mourinho is unconvinced that the Belgium international is ready to lead the line for a club competing for major honours both domestically and in Europe.
With Wayne Rooney - Mourinho's main transfer target this summer - set to stay at Manchester United, the transfer of Eto'o to west London makes perfect sense.
The 32-year-old has scored goals wherever he's gone - and there's every chance that he could score at least 20 goals this season with service from the likes of Oscar, Eden Hazard and, providing he stays, Juan Mata.
Eto'o will arrive for a relatively cheap transfer fee - although, admittedly, his huge wages will still make it an expensive deal for Chelsea - and with the clock ticking down to transfer deadline day, it's unlikely that the Blues could bring in a better striker at such short notice.
He might be on the wrong side of thirty now, but Eto'o remains a lethal finisher, while his pace and movement has not deserted him either.
Tying him up on a two-year deal would be a tremendous coup for the Blues, who would undoubtedly be a more formidable outfit with the African icon than without him.
Chelsea looked somewhat toothless on Monday night, but that will all change once they add this particular Indomitable Lion to their ranks.
