Chelsea are closing in on a deal for Inter Milan midfielder Fredy Guarin in the January transfer window.
A deal has been discussed between the clubs and personal details have been outlined, but the deal will only be done if Chelsea match or move closer to the asking price of £15million
The Colombian was also linked with Manchester United in the last week, but Mourinho is close to landing the 27-year-old.
Mourinho tried but failed to sign Guarin, who can play in the middle or right of midfield, while at Real Madrid last season.
Guarin has 47 caps for Colombia, and has had spells at Saint Etienne and Porto before his move to the San Siro in 2012.
The move could allow the likes of Kevin de Bruyne to leave the club on loan, and could seal the end of Michael Essien’s time at the club.
