“This kind of match will help us during the season” (Champions League)

Is it also due to the fact of having played three matches in one week, with a big derby (11-0 victory) on Saturday evening?
It's possible. We don't know how to manage. When we see that we are leading with a fairly large score, we always want to attack like the last match we played against Saint-Etienne, we leave feathers. When you continue every three days, you need freshness. They also played on Sunday, everyone is playing, that's no excuse. I just think that tonight, tactically, at the start we lacked precision, the little centimeters which, in the end, make the difference. We rectified this at the end in the dry cleaners.
