REF’s picks

Académica de Coimbra hold the historical pedigree and home advantage at the Estádio Cidade de Coimbra, making them slight favourites to progress in this Taça de Portugal tie. Amarante arrive with defensive frailties on the road, though their recent cup displays suggest they will not go down without a fight.

1. 1Home support in Coimbra gives the hosts a crucial psychological edge in knockout football.
2. 2Amarante have shown vulnerability away from home against organized sides.
3. 3Cup ties often bring unpredictable tactical cautiousness, and Académica's recent inconsistent form leaves room for an upset.
