Honestly, I wouldn't put too much into this B-team result. It's likely the worst performance we'll see all season. Flick's intent to rest starters was well-founded. The B-team just wasn't up to it.
As confirmed by head coach Hansi Flick during his post-match exchange with the media:
“Casadó only has a knock. All of our players give 100%, and Marc is one of them.”
Good to hear. He's been fantastic. Busquets level calm, great pivot player.
There you go projecting again, your own hatred for everybody. Not everyone is motivated by hate like you. Maybe for once try posting on football without some bigoted remark about the teams or players?
