Unbeaten Ulsan are three points clear at the top of the table after picking up four points from the double-header with Japan’s Kawasaki Frontale on Matchdays Three and Four.

However, the 2012 winners’ recent form has been inconsistent and, without the suspended Kim Tae-hwan, they go into the game at Ulsan Munsu Football Stadium on the back of a 2-1 loss to Pohang Steelers on Saturday that leaves them second in K League 1.

Korea Republic's Ulsan knows what it takes to win the AFC Champions League and, moreover, they know what it takes to do so unbeaten having done just that in the 2012 edition.

While it is far too early to say, the 2019 version of the team is set to replicate this, they have certainly begun in similar fashion having not lost in their first four fixtures, and are one of just three sides yet to taste defeat.

The-AFC.com spoke exclusively to Ulsan's Norway-born United States international Diskerud to get his views on the tournament so far, how deep the Korean club can go, and what lies in store for Tuesday's tie with Sydney FC.

The eight sides in Groups G and H will take to the field on Tuesday, before the remaining eight teams in Groups E and F follow suit a day later in a week that should see a number of the knockout stage qualification berths decided.

All teams across the four groups are still in contention for qualification to the Round of 16, setting up some tasty encounters in the eight matches taking place across Monday and Tuesday.

As the 32 sides begin to prepare for the crucial fifth round of fixtures from which some will advance and others may fall by the wayside, join the-AFC.com as we look back on the week in numbers.
