AVS have been mixed lately - a win, some draws and a couple of losses - so they're not in great form and have looked shaky at times. Portimonense, on the other hand, are playing well, having won most of their recent games, which suggests they're the stronger side right now. When these two met before, both games were tight, with the away side winning one and AVS taking the other, and there were a few goals in each.

This looks like a close match, but Portimonense's better run of results gives them the edge. I'd say Portimonense will win.
