Chelsea are reportedly looking to make a double swoop on the Bundesliga by signing Kai Havertz from Bayer Leverkusen.
The Blues are rumoured to have already agreed personal terms with Timo Werner after triggering the £53.8m release clause in his RB Leipzig contract.
According to the Daily Mail, Chelsea have now set their sights on bringing in talented Leverkusen attacker Havertz.
It is claimed that Frank Lampard's side will have to hand over around £75m for the 20-year-old, who has a combined 22 goals and assists in 38 appearances this term.
Havertz recently became the first Bundesliga player to reach 35 goals before the age of 21 and is also thought to be a target for Bayern Munich, Manchester United, Real Madrid and Liverpool.
As well as closing in on a deal for Werner, Chelsea have already completed the signing of Hakim Ziyech from Ajax.
