RB Leipzig have added Chelsea defender Ethan Ampadu on a season-long loan.
The 18-year-old Ampadu didn't make a Premier League appearance last season after signing a five-year contract with Chelsea.
"I really wanted to work with Ethan this year. That's a slight disappointment, but it's to benefit of him. In midfield and defence we have a lot of quality, so each player is a case by case," said Frank Lampard.
