Chelsea are set to lose Martell Taylor-Crossdale to Bundesliga club Hoffenheim.
Sky Sports says Chelsea made an initial offer to keep the teenager, before it was agreed he could leave the club on a free transfer.
The 19-year old east Londoner was top scorer in the U18 Premier league in 2017 and has scored goals for England from U16 through to U20 level. He was also a member of the England U18 team that lifted the Toulon Tournament trophy in 2017.
It's understood Hoffenheim are also likely to sign another, as yet unnamed English youngster before the end of the month.
