The Emirati side endured a disappointing start to their campaign when they lost 2-0 to Lokomotiv in Uzbekistan and they will hope home comforts bring about an improved performance.

Al Wahda, who will have Salem Sultan available after suspension, have faced Al Ittihad four times in the competition(in 2010 and 2011), losing three and drawing one, and have yet to register a goal.

Gonzalo Viera gave Al Rayyan an early lead against the Saudi side, but they went on to suffer a demoralising 5-1 loss, and they have now been beaten in their past three games on the continent, stretching back to April last year.

Al Rayyan, who have never faced Lokomotiv in the AFC Champions League, last faced Uzbek opposition in the 2012 edition when they defeated Nasaf home and away before exiting at the group stage.

In their first game in the competition since 2016, Al Nassr went down 1-0 in to Al Wasl, also in Dubai, and the Riyadh side have now gone four games on the continent without registering a goal.

Al Nassr have, however, been on a superb run domestically and scored deep into stoppage time to secure a 3-2 win against Ettifaq on Friday and move within four points of Saudi Pro League leaders Al Hilal.

The Iraqi side gained a credible scoreless draw away at the Islamic Republic of Iran’s Zobahan on Matchday One in what was their first appearance in the competition since 2007.

Al Zawraa have twice faced Emirati opposition in the AFC Champions League, when they lost one and drew one against Al Wahda in the 2007 group stage.

Historic wins, debut victories and record-breaking goals were all part of an action-packed Matchday One, so join the-AFC.com as we look back on the facts and figures that caught the eye.

A superb performance from Daegu FC forward Cesinha in his side's 3-1 debut win away at Australia's Melbourne Victory in their Group F Matchday One clash on Tuesday saw the Brazilian pick up this week's top player plaudit.

Cesinha was directly involved in all of Daegu's goals against Melbourne Victory (three - one goal, two assists); more goal involvements than any other player in the 2019 AFC Champions League opening round.
