The defending V-League champions made a strong start to the new league campaign, but have stumbled slightly of late, losing two of their last three matches.
Despite this, Thanh Son is feeling positive heading into Tuesday's clash even though they are without two key players.
“Shandong Luneng is a very strong opponent. They have many good professionals and good foreigners,” Thanh Son told the official AFC website.
“We will not have two important players Xuan Luan and Dinh Luat, but I still believe in the others who always want to show their best in an important game like this.
“We're also are having good performances during V-League matches and an advantage to play at home, so with that I hope we will have a good result.”
