Chelsea have been the most active English club in the transfer market this summer, making six signings in total.
The latest deal they're touted to complete could be the best of the lot, however, as a Champions League winner could be heading to Stamford Bridge.
What makes this even more of a surprise is the nature of the deal, as the Chelsea hierarchy look set to make a clever, astute deal in the window.

According to Spanish outlet AS, Chelsea are looking to offer Real Madrid their goalkeeper Kepa Arrizabalaga in exchange for Andriy Lunin.
Kepa, of course, spent last season on loan at Real Madrid, filling in for the injured Thibaut Courtois. After 10 consecutive games in goal for Carlo Ancelotti, though, Lunin quickly overtook him in the pecking order, with the Ukrainian playing the majority of the rest of the season.
Indeed, Lunin started every game in the Champions League knockout stages - except the final, which Courtois returned for - as Real Madrid lifted their 14th trophy in the competition. Real Madrid's £25m valuation is deemed too high by Chelsea, however, while Lunin himself wants to leave the Bernabeu in search of guaranteed minutes.
The report suggest that such is Chelsea's desire to land the 25-year-old, they're willing to offer Kepa, who cost them £72m in 2018, in exchange for Lunin. Real Madrid, though, are seeking cash-plus-player, with Lunin valued higher than the Spaniard.
That seems justified, too. Transfermarkt believes Lunin is worth £21m, while Kepa is valued at just £10m. Crucially, though, the Spaniard is reportedly happy to act as Courtois' back-up, despite the 29-year-old approaching key years in his career.
In FourFourTwo's view, this doesn't seem like a deal that will happen this summer - despite it making clear sense for all parties involved. Currently, it looks like the Blues are set to land Filip Jorgenson from Villarreal instead - but should that deal fall through, we expect the Chelsea hierarchy to make a push for Lunin.
