Kai Havertz has undergone his medicals with Chelsea, as the club puts final touches to his transfer from Bayer Leverkusen, BILD reports.

The 21-year-old is believed to have completed the medical on Sunday.

Both clubs have agreed a stunning £90million deal for Havertz, which will see him become the most expensive German player of all-time and Chelsea’s new club-record signing.

Chelsea will pay an initial £70m with £20m in add-ons for the Germany international.

Havertz is set to sign a five-year-deal at Stamford Bridge.

Havertz joins the likes of Hakim Ziyech, Timo Werner, Ben Chilwell and Thiago Silva, who have all completed their transfers to Chelsea ahead of the new season.

The attacking midfielder will be officially unveiled by the Blues in the coming days.

His arrival takes Frank Lampard’s spending this summer past the £230 mark.

Chelsea will need to register Havertz before Thursday if he plays for Germany to be able to apply for an exemption on sporting grounds for him so he therefore doesn’t have to quarantine in the UK upon his arrival from international duty. Otherwise he could miss the start of the 2020/21 Premier League season.

They kick off their campaign away to Brighton and Hove Albion on September 14.
