As per The Athletic, Chelsea are aggressively pursuing Nathan Ake of Manchester City and are hoping to sign him within the next week.
Chelsea are in advanced talks over the Koulibaly deal as well, with Tuchel looking to sign three defenders this summer.
Ake will likely cost Chelsea £45 million and sources suggest talks are being held over the structure of the deal, while the personal terms are not an issue.
Chelsea have already got the Sterling deal done with City for £47.5 million and are set to unveil the player once he joins the team in LA for the pre-season tour.
