Local Algarve League team Silves FC travel to Rio Ave, currently fifth in the Primeira Liga two points below Benfica, in the fourth round of the Portugal Cup on Sunday.
The only team from the Algarve still in the competition have created club history by reaching the last 32.
Tomás Costa, who scored the winner for Silves in the last minute of extra-time in the third round against GD Chaves ‘B’, will be hoping for another major upset.
