The competition will resume in just over a week's time as the eight remaining sides continue their quests to be crowned Continental champions, but before looking ahead to the latter stages, take a look back at the-AFC.com's Week in Numbers.

Abdulfattah Asiri’s 42nd minute strike was the difference at the final whistle at King Saud University Stadium, but a 4-2 victory in Jeddah a week earlier ensured Al Hilal progressed to the quarter-finals for the seventh time in their history.

The Brazilian midfielder struck twice from inside the box, either side of the half-time break to help his side to a 4-3 aggregate win after Abderrazak Hamdallah had cancelled out Al Wahda’s opener.

Al Sadd saw off the challenge of Qatar rivals Al Duhail, scoring a 3-1 win in the second leg of their Round of 16 tie to advance 4-2 on aggregate.

Strikes by Akram Afif, Abdelkarim Hassan and an own goal by Ahmed Yasser secured Al Sadd the win but Spain and Barcelona legend Xavi said it was a team effort that took Al Sadd to a quarter-final tie against Saudi Arabia's Al Nassr.
