Disaster Index: 7.1 Entry: The Neymar Variable Cause: Neymar returning to fitness for Brazil's group fixture against Scotland, converting the anticipated opponent into a different order of problem. Category: Structural Evidence: Neymar absent from competitive football for an extended period prior to this tournament. His return to the Brazil squad was confirmed ahead of the Scotland fixture. Scotland have faced a player of this classification once in a World Cup context: Argentina, 1978. The record is available. Historical precedent: Scotland's capacity to contain elite individual talent in tournament football has not been formally established. The evidence column remains sparse. Affected parties: Scotland defensive structure. Steve Clarke's preparation assumptions. Anyone who had filed Brazil under manageable. Immediate outlook: The Disaster Index is not in the business of discouragement. It is in the business of classification. A fit Neymar against a Scotland side that has already used its emotional reserves on the opening group stage constitutes a structural condition, not a tactical one. Structural conditions are filed, not solved.
