Kai Havertz is unlikely to train with Bayer Leverkusen again, says head coach Peter Bosz, as he closes on a £90m move to Chelsea.
The Blues have been in talks with their Bundesliga counterparts for several weeks over a deal for the Germany international, who is keen to join the club as soon as possible.
Havertz is currently with the German national team ahead of their Nations League fixtures against Spain and Switzerland this week.
Asked if he expected the 21-year-old to return to Leverkusen at the end of the international break, Bosz said: “Unfortunately our squad isn’t set yet. I don’t expect (Kevin) Volland and Havertz to train with us again.
“It’s possible more players will transfer. We definitely still have to add some players.”
Havertz looks set to become Frank Lampard’s seventh summer addition, hoping to join international team-mate Timo Werner, Hakim Ziyech, Ben Chilwell, Thiago Silva, Malang Sarr and Xavier Mbuyamba.
He has spent his entire career at Leverkusen, contributing an impressive 36 goals and 25 assists in just 118 Bundesliga appearances since making his debut in October 2016.
It would represent a major coup for Chelsea to secure the signing of Havertz, who has received interest from some of the biggest clubs in Europe.
