RB Leipzig coach Julian Nagelsman praised Ethan Ampadu for his performance in victory at Champions League opponents Tottenham.
The occasion and performance was the biggest moment of Ampadu's career and the on-loan Chelsea defender has won over his coach.
"Ethan proved at Tottenham that we can trust him," said Nagelsmann.
"Whether he will play against Schalke 04 depends on what some of the other players' situation looks like.
"There is no reason why (DAyot) Upamecano should not play, but it may be that we find a place for Ethan anyway."
