Late goals from Lewis Baker and Nathan Ake ensured they preserved their 100 per cent record in the UEFA Youth League, making it nine points from nine with a hard-fought 2-0 win away at Schalke.
Blues coach Dermot Drummy told chelseafc.com: "Their game-plan was to press and stop Lewis Baker getting us out from the back and it worked in the first half.
"Our mistake was to keep trying to play on a pitch that wasn't conducive to that.
"We didn't win enough second-balls in the first half but we improved in the second and got back into it, and I felt we deserved the win in the end.
"They've shown the type of mentality we need at the club, we've kept our heads and the players have done admirably."
