Yemen hosts Hong Kong in the second Asian Cup qualifier in Group A.
Both teams are coming off losses but Yemen coach Sami Al Nash believes his side's fighting performance against Japan last time holds them in good stead.
"I'm optimistic that we can have a good match following the good result that we got against Japan," said Al Nash.
"The players played well even though it was an away game and we had a long trip.
"The game against Hong Kong is important because we will be playing at home and we are looking to get a win in order to get back into contention. We want to win even though the match will not be easy."
Hong Kong coach Dejan Antonic was hoping his side could bounce back from a 3-0 loss to Bahrain.
The match against Bahrain was very difficult for us but we have shown that we have discipline and a fighting spirit," the Serbian said.
"It was a good experience for us and what was more important is that we played against a tough team.
"I hope that we can recover against Yemen and get a good result but it will not be an easy match."
