Chelsea have bid a British-record £105m for Benfica star Enzo Fernandez.
The Blues' pursuit of the World Cup winning Argentinian midfielder appeared dead in the water after the Portuguese side stood firm on the mammoth release clause.
But SunSport reported last week that one final push was being planned to land their man.
And after several rejected bids, Chelsea look set to finally get a deal over the line for the 22-year-old just hours before Tuesday's January transfer deadline.
Following meetings between the two clubs on Monday, the plan is to pay the sum in six instalments in order to stay within Financial Fair Play (FFP) regulations.
Should it go through – surpassing the £100m paid by Manchester City for Jack Grealish – American owner Todd Boehly will have splashed over half a BILLION on new players.
It would also be club-record signing, beating the £97.5m paid to Inter Milan for Romelu Lukaku in August 2021.
