Jorge Jesus' men could lift their first Primeira Liga in three years with victory, while the Dragao would go top if they can triumph in front of their own fans.
Porto will be able to call on the talents of Alex Sandro after the Brazilian fullback recovered from a muscle strain to be declared fit. The ex-Santos man has been training throughout the week and is said to be at 100 percent for the decisive clash, although Maicon, who trained apart from the rest of the Dragao, is still an uncertainty.
Benfica will give Argentina international Enzo Perez until the last minute to prove his fitness. The 27-year-old was expected to miss Saturday's encounter with a thigh strain, but he has shown improvements in training and could still make it.
