At the international stage, neighbouring countries Southeast Asian countries Indonesia and Malaysia's rivalry runs deep. Although their footprints at the continental level are minimal (they have only one senior regional title between them, Malaysia's 2010 AFF Championship win), any encounters between the two national teams are sure to produce fireworks on and off the pitch. Case in point? Their most recent two clashes, back in 2019, in the World Cup Asian qualification.
However, there have been instances whereby figures from one of the two countries were able to transcend nationalistic boundaries, by making the successful leap into the other country's domestic league.
