Chelsea forward Kai Havertz is believed to have asked to wear an unusual shirt number for the Blues this season, following completion of his £72m summer transfer from Bayer Leverkusen.
Chelsea added Havertz to their burgeoning forward line last week and the Germany international will be expected to make his debut alongside fellow new faces Timo Werner and Hakim Ziyech when the club’s Premier League campaign begins on Monday night against Brighton.
