Al Sadd, coming off a dominant domestic season which saw them lift the Qatar Stars League title unbeaten, will be aiming to maintain that form as they look to add to the AFC Champions League title won in 2011.

Foolad will be heading into the match with full confidence after their emphatic 4-0 win over UAE's Al Ain FC in the playoff just three days ago to qualify for the group stage for the fourth time in their history.

With no shortage of attacking talent on display, we shine the spotlight on six frontmen who are on fire in their clubs’ domestic campaigns and could be set to bring those hot streaks onto the Asian stage in this year's continental club competition.

Some of these starlets are established players for their club sides and some have even appeared in previous AFC Champions League seasons, while several are just breaking into the starting XI, but those U23 players are all eyeing a milestone campaign over the next three weeks.

With the 20 remaining teams from East Asia set to begin their continental campaigns a little later in the year, the-AFC.com looks at some of the numbers that stand out ahead of the start of the 19th edition of the AFC Champions League.

An intriguing Group D in Riyadh will see Al Wehdat become the first side from Jordan to ever appear in the competition as the Amman club will go up against Qatar's Al Sadd SC, Iranian team Foolad Khouzestan and hosts Al Nassr.

With the opening round of fixtures taking place on Wednesday, the-AFC.com looks at the stadiums, key players and games to keep an eye out for.
