Here is your Chelsea transfer roundup on Monday, June 26.
Mason Mount stance
Manchester United have kept their £55million bid for Mason Mount on the table for Chelsea to accept, but won't enter face-to-face negotiations to reach an agreement. That's according to the Telegraph, which claims that the Red Devils have taken a "very dim view" of Chelsea's negotiations for the midfielder.
It has resulted in the side looking towards alternative targets in the transfer window, however their preferences remains strongly on signing Mount. The 24-year-old has just one-year remaining on his contract at Stamford Bridge, opening up the possibility of a free transfer.

Kalidou Koulibaly deal confirmed
Chelsea have confirmed the exit of Kalidou Koulibaly, who joins Saudi Arabian side Al-Hilal after just one year with the Blues. The defender joined from Napoli last summer to bolster the defensive ranks, but the veteran struggled to adjust to the side, eventually leading towards a move away as part of a wider squad overhaul.
A statement from the club reads: "Kalidou Koulibaly has left Chelsea after completing a permanent transfer to Saudi Professional League side Al-Hilal. We would like to thank Kalidou for his contributions on and off the pitch during his time at Stamford Bridge and wish him well for the next stage of his career."
Nicolas Jackson medical
Nicolas Jackson has completed his medical ahead of a move to Chelsea this summer, according to various reports, with final details waiting to be sorted before a deal is complete. The young striker looks set to become the third signing of the Mauricio Pochettino era, with hopes of solving the goal scoring issues at the club.
