Cristiano Ronaldo's Al-Nassr crashed out of the Asian Champions League in the quarter-finals after the Saudi Pro League side lost 3-1 on penalties to Al-Ain in a pulsating game on Monday.

Al-Nassr overturned a 1-0 first leg deficit to win 4-3 on Monday but with the contest ending 4-4 on aggregate, the players headed into a shootout from which Al-Ain prevailed.

Al-Nassr's foreign imports Miroslav Brozovic, Alex Telles and Otavio all failed to score from the spot as the side from the United Arab Emirates advanced to the semi-finals, where they will face either Al-Hilal or Al-Ittihad -- both from Saudi Arabia -- next month.
