After the last minute draw with Boavista, Belenenses's are now seven games without a win.
Rio Ave were knocked out of the cup quarter finals in midweek after drawing 4-4 with Aves in extra time. Coupled with the fact their standout performer has left the club, morale will have taken a hit in recent days.
Belenenses are tough to beat at home, but they are struggling to score goals at the moment. On their day, Rio Ave will be hard to beat.
Sporting come in to this match after a 5-0 win over Marítimo in the league and hard fought 2-1 win over second-tier side Cova da Piedade in the cup on Wednesday. Still unbeaten in the league, they have kept clean sheets in six of their nine home games.
Aves will be high on confidence after overcoming Rio Ave on penalties in the cup, having drawn 4-4 after extra time. This could prove a defining point in their season as they are two points above the relegation zone. However, they would have wanted to go anywhere that the José Alvalade right now.
