Campbell's center back performances in the first three matches of the group stages in AFC Cup group G. Preah Khan Reach Svay Rieng FC made history whenever they defeated Bali United FC (Indonesia Champions) giving the Cambodian side their first ever AFC Cup group stage victory. AFC Cup group G is not an ideal group for the Cambodian side as it's filled with ASEAN powerhouse teams such as, Ceres-Negros FC (Philippines Champions & #1 Ranked Club in Southeast Asia Football), Bali United FC (Indonesia Champions) and Than Quang Ninh FC (3rd place in V-League, Vietnam). This provides a great opportunity for Svay Rieng FC from Cambodia to test themselves against some of the best clubs Southeast Asia has to offer.
