The transfer of Kai Havertz from Bayer Leverkusen to Chelsea has been on hold for one reason.

Bayer are stopping Chelsea from completing the transfer of the 21-year-old because they fear it could restrict their efforts to sign a replacement, according to Bundesliga expert Jan Aage Fjortoft.

“Seems like the main – reason for the delay of a public confirmation of the deal, is that Leverkusen would have liked to be further in replacing him,” Fjortoft tweeted.

“It’s strategy. After a big Havertz fee any replacement will be more expensive. That’s the name of the game.”

Nicolò Schira reported that the deal has been agreed with the two clubs, and that Chelsea will pay the Bundesliga club £72million up front, with a further £18m in add-ons and instalments.

Overall, Bayer want to find a suitable replacement for their departing superstar, before allowing the full announcement of Havertz sale.

Right now, Chelsea look like they are signing a player each day and Chelsea fans are waiting to know which day that announcement will be.
