PSG captain Marquinhos admits their defending fell short in defeat at Manchester City.
PSG lost their latest Champions League group game 2-1 last night despite going ahead.
Marquinhos later said: "We have to work on the details. I think we can improve on that, especially defensively. We know we have a big offensive force. If we manage to manage the defensive aspect well, and we come to know that it is a collective aspect...
"Everyone has to do better so that we take fewer goals. Afterwards, we will score because we really have good strength up front."
