In 2022, soon after the takeover of the Blues, new co-owners Todd Boehly and Clearlake Capital attempted to bring in Raphinha from Leeds United.
However, like they later did with Sevilla defender Jules Kounde, the Premier League outfit lost out to Barcelona in the race for his signature.
Since his arrival at Camp Nou, Raphinha can claim to have enjoyed a successful stint, winning a La Liga title and contributing 14 goals and 19 assists from 70 appearances in all competitions.
Nevertheless, at a time when Barcelona's financial issues have been well-documented, it has been suggested that Raphinha is viewed as their most sellable asset.
As it stands, the 27-year-old may see no reason to depart Barcelona courtesy of making regular appearances, albeit some of them coming from the substitutes' bench.
That said, there is likely to only be increasing interest in Raphinha's services if clubs - particularly Premier League teams - are aware of his availability.
According to Fichajes, Chelsea remain interested in trying to entice Raphinha to Stamford Bridge in the next transfer window.
With Boehly and Clearlake Capital having spent in excess of £1bn across their first three transfer windows, Chelsea have just endured a January where they made no senior additions.
Unless things changes, there appears little prospect of any of that quartet leaving Chelsea due to their long-term contracts, yet Raphinha seemingly appears high on the club's shortlist.
A recent report claimed that Chelsea must first make numerous sales in the summer, before their next accounts are due on June 30, if they are to fully comply with the Premier League's Profit and Sustainability regulations.
Should that prove to be true, Chelsea would have to wait until July to make their move, a situation that would not suit Barcelona at a time when the Catalan giants need to make widespread cutbacks of their own.
