Bayer Leverkusen chief Rudi Voller claims Chelsea took advantage of the coronavirus crisis to sign Kai Havertz.

Chelsea sealed move for the Germany international after weeks of negotiation with the Bundesliga club, who were desperate to hold on to the highly-rated youngster.

But the west London club were equally determined to sign Havertz, and eventually paid £72m to get their man.

He told Bild: “[Chelsea] simply made good use of the coronavirus period.

“Next year it would have been much harder for Chelsea to get Kai. [Other interested teams] preferred to hold back because of the high transfer fee in this special and uncertain time.”
