The super deal on the radar of Frank Lampard may costs his side, Chelsea more than what they thought as they may end up paying more than £90million for top target Kai Havertz.
Germans Bayer Leverkusen are resigned to losing the impressive forward with Chelsea close to a deal.
But they want £63m up front plus add-ons that would take the fee above £90m.
Frank Lampard’s Blues have already signed striker Timo Werner and winger Hakim Ziyech.
And closure on a deal for Havertz, 21, would take Chelsea’s spending to more than £170m.
That will wipe out the £150m banked, add-ons permitting, when they sold superstar Eden Hazard to Real Madrid this time last year.
