Chelsea and Bayer Leverkusen remain far apart on their valuation of Kai Havertz, according to a report.
The Blues are looking to bring in the Germany international as their third addition ahead of next season, having already signed Hakim Ziyech and Timo Werner.
However, the clubs have been unable to reach an agreement over a fee for Havertz, who has scored and assisted a combined 38 goals in the last two Bundesliga seasons.
Sky Sports News reports that Leverkusen rate the 21-year-old at €100m (£90m) and will not budge on that valuation, regardless of the financial impact caused by the coronavirus pandemic.
The Bundesliga side are also said to be confident that they can ask for even more for their prized asset in 12 months' time given his current trajectory.
