Nam said Al Sadd performed well but mistakes cost them the match.

“We lost but I’m happy with our performance,” Nam told the-AFC.com. “We had a good performance and created many scoring chances.

“We played very well and we controlled the match. However, we made some mistakes and in matches against good teams, when you make mistakes, you will lose.”

The midfielder said fatigue took its toll on the Qatar Stars League champions but they are looking forward to Tuesday's play-off for fifth place against Esperance Sportive Tunis.

“We lost to Monterrey because we played two extra periods in the previous match against Hienghène Sport,” he said. “We were extremely exhausted.

“We still have one match to play and we must do our best to win.”
