Benfica, the football club with the largest number of paying members worldwide, are the opponents of Olhanense at the Algarve Stadium, Faro, on Sunday evening – kick-off 6.15pm.
The Eagles will be striving to keep in touch with league leaders Sporting Lisbon who have a two-point advantage over their bitter rivals.
The Lisbon side dropped valuable points at home to lowly Arouca last weekend whilst Olhanense are in the relegation zone without a win in nearly two months.
Tickets can be purchased from the José Arcanjo Stadium, Olhão (behind McDonalds on the EN125) until midday on Saturday. Alternatively tickets will be available at the Algarve Stadium prior to the game.
With or without a ticket, fans are advised to arrive early.
Olhanense manager Paulo Alves has defensive worries with Jander still absent through injury and Seric banned after being sent-off against Rio Ave.
Olhanense will have a few days to recover after the Benfica game before travelling to the north to play champions FC Porto next Friday (December 20) kick-off 7pm. The game is live on Sport TV.
