Nacional have been in poor form recently, losing three of their last five matches, though they did manage two wins away from home. Guimaraes have also had a mixed run, with two wins, two losses, and a draw in their last five games, but they are coming off a strong 1-0 away victory. The recent head-to-head meetings between these two sides have been tight, often with a few goals. The last three games all had two or more goals, including a 2-2 draw and a 2-1 win for Guimaraes.

This looks like a very close match, with both teams showing similar levels of form and strength. Guimaraes have a slight edge in their recent head-to-head results and are in decent shape after their last win, while Nacional are a bit inconsistent. A draw seems the most likely outcome, as neither side looks dominant enough to clearly win, but Guimaraes are a strong bet to avoid defeat.
