Chelsea are pushing to complete the signing of 21-year-old Kai Havertz from Bayer Leverkusen and will next look to agree a fee after establishing that the German wants to move to Stamford Bridge.
Discussions have primarily been conducted through Havertz's entourage so far and qualification for next season's Champions League through a top-four finish has only strengthened the west Londoners' hand.
The Blues were waiting to see the outcome of their league campaign before doing further business after completing the double signing of Timo Werner and Hakim Ziyech for a combined fee of £91 million (€100m/$114m).
