Chelsea are currently the most active team in the transfer window this season as Blues set to make another announcement as soon as possible.
However, Thiago Silva would become the fourth Chelsea signing of the summer after Timo Werner, Hakim Ziyech and Xavier Mbuyamba
According to Sky Sport, Thiago Silva is due to undergo a Chelsea medical on Thursday – despite last-ditch efforts by Paris Saint-Germain to offer him a new deal.
The finishing touches to an offer have been agreed between Chelsea and the 35-year old Brazilian in the past 48 hours.
PSG manager Thomas Tuchel remains a huge advocate of Silva – and has continued this week to try to keep the former AC Milan defender in Ligue 1 for a ninth season.
Chelsea have been keen to strengthen having been banned from signing players last summer. The London club could also complete deals for Leicester left-back Ben Chilwell and Bayer Leverkusen forward Kai Havertz before the start of the new season.
Silva won seven Ligue 1 titles during his time in France, but leaves the club having failed to achieve the European success desired most in Paris.
