Chelsea are on the verge of sealing a £90million deal for Bayer Leverkusen sensation Kai Havertz. 

Reports suggest Havertz, 21, will become Frank Lampard ’s latest summer recruit this week, following Hakim Ziyech and Germany team-mate Timo Werner to Stamford Bridge. 

And the Blues are not expected to conclude their transfer business there, as Leicester left-back Ben Chilwell and out-of-contract Brazil defender Thiago Silva are also said to be on their way to the club. 

Having not made any new signings over the past year, and following the £100million sale of Eden Hazard last summer, Chelsea have more than enough in the bank to fund Lampard’s squad revamp.

Yet according to Sport Bild , the west London club will not be paying Havertz’s £90million fee upfront. 

It is believed Leverkusen will receive an initial £72million for the midfielder, with a further £9million to come based on expected performance - such as qualifying for the Champions League - and another £9million to come from potential trophy success.
