Nguyễn Trọng Hoàng

After the departure of Le Cong Vinh to Hà Nội T&T F.C. in 2009, Hoang was given Vinh's number 9 and since then, he has become an important part of Sông Lam Nghệ An. His performance helped SLNA win third place in the 2009 V-League season and 2010 Vietnamese Cup title. In the financial turmoil that affected most V-League clubs after the 2012 season, SLNA was unable to arrange a financial contract with Nguyen. The contract between Nguyen and SLNA expired on 2 January 2012.[3]

In 2007, Hoang was in Alfred Riedl's plan for the 2007 Southeast Asian Games. However, he was left out because he had to take the final exam for his high school studies.

In 2009, Hoang was again chosen to play in the 2009 Southeast Asian Games by Henrique Calisto. Hoang scored in the third game of the tournament against Malaysia. However, he was injured when he played against Cambodia, which prevented him from playing in the semi-final. In the tournament's final, Hoang came on as the substitute but the team lost against Malaysia in the final and received the silver medal. Despite the loss, the team's performance in the tournament was impressive enough that Hoang is one of the few players who were called up to play in the national team.

In 2010, he was again chosen to play in the 2010 Asian Games in Guangzhou, in which he scored two goals against Turkmenistan and Bahrain to help Vietnam proceed into the second round for the first time in history. The team lost to North Korea, but he was then selected to play in the 2010 AFF Suzuki Cup. In the first game, Hoang scored two goals against Myanmar after he came on at the 72–minute. The team came on to win 7–1.[4]
