The high-flying QNB Stars League champions Al Sadd will be looking to maintain the top spot in Group D while Al Duhail will target their third win in Group C to grab one of the eight places in the 2019 AFC Champions League (ACL) knockout stage today.
Al Sadd and Al Ahli face-off in Doha 364 days after their last encounter at the same stadium in the 2018 Tournament's Round of 16.
Then, Al Sadd emerged 2-1 winners, laying the foundations for quarter-final progression, having earned a 2-2 draw in the reverse fixture in Jeddah a week later.
This time around, Al Sadd are a point ahead of their opponents and the three points today would put the winning side in a comfortable position, although official qualification may have to wait until the final matchday nevertheless.
Every team in Group D could still finish top or bottom, with just three points separating leaders Al Sadd from fourth-placed Persepolis.
The match kicks off at 9:45pm.
Last year's finalists, Persepolis have lost both their away trips this campaign, but they need a result when they travel to Taskhent for the clash of Pakhtakor today. The Iranians are bottom of the group with four points, just one behind their hosts.
Al Duhail sit on a tough group that boasts four of the Continent's finest sides and all of them will go through turmoil ahead of a decisive round.
Al Duhail turned on the power in the second half to beat Esteghlal 3-0 in their opening 2019 ACL Group C tie in the previous marchday and will be keen to repeat the same in today's away game.
Esteghlal who have swapped coaches since their last continental outing, will be led by Farhad Majidi, who replaced Winfried Schafer, when they welcome Al Duhail to Azadi Stadium. Any result except a win will send the Iranians out of the competition early and Rui Faria will be looking to make sure his men will do their best to ekiminate the Iranians.
The kick off is at 7:00pm Qatar time.
Tomorrow, Al Rayyan cannot afford to lose against Al Ittihad in doha and they will be looking to give their best to avoid a third consecutive defeat. Al Ittihad return to continental action off the back of a disappointing domestic defeat to Al Tawoun in the King's Cup final.
The two-time AFC Champions League winners are second in the table with seven points and a win on Tuesday will see them through to the knockout stage for the first time in five years.
