The Austria international signed for SIPG from Premier League side West Ham United in July and has had an immediate impact, scoring four times in six league games.

But his arrival – which saw Brazilian striker Elkeson return to Guangzhou Evergrande – has given Yu and his teammates a confidence and quality boost ahead of their AFC Champions League quarter-final meeting with the Japanese side.

Urawa, who won last season’s Japan's Emperor’s Cup to qualify for the 2019 AFC Champions League, face Vitor Pereira’s side in the first leg of their last eight clash in Shanghai on August 27 knowing the last 18 months have been a difficult period for the two-time champions.

In the season-and-a-half since Urawa captured their second AFC Champions League – which came a decade after their first – the club has experienced significant upheaval.

There was no shortage of drama in the four fixtures which saw a come-from-behind victory, some fabulous goals and domestic bragging rights earned. Here's what those involved had to say.

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.
