Bayer Leverkusen midfielder Kai Havertz has reportedly passed his medical for Chelsea ahead of his proposed club-record move to Stamford Bridge.
The 21-year-old is expected to put pen to paper on a five-year contract with the free-spending Premier League side after they agreed terms with Leverkusen for the in-demand playmaker.
The deal is thought to be worth an initial €80m (£71.3m), with that fee potentially rising as high as €100m (£89m) with add-ons.
German outlet Bild reports that Havertz underwent his medical in London on Sunday and Chelsea are now understood to be working on the official confirmation of the deal.
Recent reports claim that the paperwork between the two clubs has been signed for more than a week.
Frank Lampard's side have been one of the busiest in the transfer market this summer, already bringing in Hakim Ziyech, Timo Werner, Thiago Silva, Malang Sarr and Ben Chilwell ahead of the imminent arrival of Havertz.
The latter deal will surpass the £72m Chelsea paid to sign goalkeeper Kepa Arrizabalaga in 2018.
