A win for Benfica on Sunday would secure their eleventh domestic double, and would represent their third piece of silverware this season after the Supertaça and Primeira Liga. The Eagles are gunning for their 26th Taça de Portugal crown (in its modern format). Benfica last reached the Portuguese cup final in 2013/14, when they overcame Rio Ave thanks to a solitary goal from Nico Gaitán.
Rui Vitória has already tasted victory in the competition; in 2013, he masterminded Guimarães' 2-1 triumph over Jorge Jesus' Benfica. The 47-year old also has an excellent record against his opposite number Pedro Martins; in 16 meetings, Vitória has claimed eight wins and four draws. Benfica and Guimarães have already met three times this season, with the Lisbon giants prevailing on each occasion, scoring nine and conceding zero.
The two clubs last met just a fortnight ago, as Benfica strolled to victory at the Estádio da Luz to claim a fourth consecutive league title. The visitors came into the game needing all three points to have any chance of overhauling Sporting in third place, but Benfica seized the initiative with a quickfire double from Franco Cervi and Raúl Jiménez. The final scoreline of 5-0 flattered Guimarães, and Pedro Martins must have been bitterly disappointed by the lack of fight shown by his players.
A repeat performance on Sunday seems highly unlikely, especially as Os Conquistadores had a positive campaign, playing some of the most attractive football in Portugal. Despite their collapse in Lisbon, the northerners completed the season with the second best away record in the Liga NOS. Between February and May, Guimarães were virtually unstoppable in the league, embarking on an eleven-match unbeaten run that included eight victories. By finishing fourth, they clinched qualification for next season's Europa League.
Although they lost Tiquinho Soares to FC Porto in the January transfer window, Pedro Martins' squad still boasts the goal threat of wingers Moussa Marega and Hernâni - both on loan from FC Porto - who have each made it to double figures in all competitions. Attacking midfielder Paolo Hurtado has also chipped in with nine goals in 39 appearances, while ex-Benfica right-back Bruno Gaspar (pictured below) has impressed in defence.
In goal, it will be interesting to see whether Martins opts for Brazilian veteran Douglas, or Portuguese starlet Miguel Silva, who has been persistently linked with a move to Benfica. Silva only made four league appearances in 2016/17, but was given the nod in six out of nine cup clashes.
As ever, one should expect few surprises from Rui Vitória. With the exception of Jardel, the Benfica coach has a fully-fit squad to select from, and he is likely to keep faith with the players that delivered the Tetracampeanato. Andreas Samaris is free to take his place in the squad after the Eagles appealed his four-match suspension for punching Moreirense's Diego Ivo. Although the suspension is unlikely to be overturned, it will now be delayed until next season. Ederson could be making his farewell appearance at the Jamor, with the Brazilian shot-stopper widely expected to join Manchester City this summer.
Arguably the most difficult decision for Vitória is who should partner Jonas in attack. Kostas Mitroglou remains Benfica's top scorer in 2016/17, with 27 goals in 43 appearances. He has been particularly lethal in the Portuguese cup, netting an incredible nine times in five matches. Nonetheless, the Greek international has looked lethargic in recent weeks, which is perhaps understandable following the birth of his son. Raúl Jiménez has endured an injury-ravaged campaign, but the 26-year old has looked sharp whenever he has been fit. The Mexican offers greater mobility than Mitroglou, and he averages a goal every 109 minutes this season, which compares favourably with Mitroglou's average of 119 minutes.
To add extra intrigue to the encounter, Sunday's final will be the first major Portuguese match to feature video assistant referees. Artur Soares Dias (pictured below) and Jorge Sousa will be the men behind the television screens. Although Rui Vitória is strongly in favour of video technology, he has questioned the decision to introduce it in such an important fixture.
