Awal, who is currently nursing a knee injury, scored three goals during the group stage of the competition, in which South China maintained a perfect record by winning all six of their matches.
Even though the Cameroonian has not trained since suffering the injury against Eastern AA in a play-off game last week, he is eager to play against Bengaluru.
"I want to play," Awal told the South China Morning Post. "I know it is very important and it's up to the coach to make the final decision."
However, South China assistant coach Ricardo Rambo believes that it will be a major setback if Awal is unable to play on Tuesday.
"His presence can make a big difference and of course we want him to play," Rambo said. "He told me [yesterday] he is getting better and we just keep our fingers crossed."
Bengaluru are currently in second place in the I-League and have a chance to be crowned champions if they beat leaders Mohun Bagan in the final game of the season this weekend.
Rambo knows that Bengaluru will be looking to head into their match against Mohun on a high by beating South China and booking their spot in the quarter-finals of the AFC Cup, which will begin in late August.
"They may have an important match back home, but it doesn't mean they won't give their best in Hong Kong," he said. "They have some quality overseas players and their domestic legion is also strong."
