Nacional have been in poor form lately, losing three of their last five games and winning just twice. Gil Vicente have also been inconsistent, with two wins, one draw, and two defeats in their last five matches. Looking at recent meetings between these two sides, the matches have seen plenty of goals - the last few encounters have all finished with at least two goals, and there were some big wins for the away side.

Both teams are struggling for consistency, which makes this a tough match to call. However, Gil Vicente have won on their last two visits to Nacional, and with the hosts in shaky form, the visitors might have a slight edge. I think Gil Vicente will win this match.
