Peter Bosz’ men missed out on qualification for the Champions League, accelerating the Germany international’s desire to leave in the near future.
Leverkusen were open to selling the 21-year-old but publicly stated that they wanted upwards of €100 million (£90m/$111m) for their prized asset.
Although Chelsea need just one win from their final two league games to seal Champions League football for next season, it is understood that Havertz would still join the Blues even if they don’t seal a place in Europe’s premier club competition.
Having scored 17 goals and provided eight assists in all competitions in 2019-20, the versatile forward has emerged as Germany’s outstanding young talent, with Frank Lampard having publicly referred to him as a “top player”.
Chelsea initially faced competition to sign Havertz, but with the financial repercussions of the coronavirus crisis taking hold, it is likely to be a far more cautious transfer market this summer.
