"We knew how important this game was, as with a victory we'd be practically qualified. We played very well, especially after that shaky start, but showed excellent character to fight back," the Argentine veteran said.
"We did not have a good start and allowed CSKA far too much space and gave away those two goals. Luckily, those two slaps woke us up and prompted us to bring out our character and pride.
"Unfortunately we are missing several key figures, but the squad is so large that we can overcome those obstacles.
"I am happy playing in midfield, but considering all the difficulties I will play wherever the Coach needs me. The important thing is to be on the field."
