Jude Bellingham is due to undergo a Real Madrid medical in the coming days.
Borussia Dortmund have announced Bellingham is being sold to Real for an initial fee of 103m.
The midfielder is set for a medical, having suffered a knee strain towards the end of the season.
It is hoped the move can be wrapped up within seven to 10 days.
Real Madrid won't confirm the signing at their end until Bellingham's medical is completed.
