Borussia Dortmund U19 coach Mike Tullberg has offered their early planning for Jamie Bynoe-Gittens.
The England U17 international has joined BVB on a free transfer from Manchester City.
Tullberg revealed: "Due to corona and a shoulder injury, he hardly trained for six or seven months. So we will build him up slowly. Patience is required.
"Currently he is only doing part of the training."
He added: "Jamie is an excellent boy, very down to earth. And a very, very great footballer."
