Currently leading Group F and guaranteed to finish as at least one of the best third-placed teams, Hungary has qualified for the last 16.
Portugal, however, has not yet secured itself a spot.
The two will clash at the Parc Olympique Lyonnais in Lyon today in the final match day of the 2016 UEFA European Championship group stage competitions.
Hungary, presently ranked 20th in the world by FIFA, has surprised football analysts as they were not among the favorites to top Group F with Portugal and Austria as the squads that were expected to share the top two spots of the group's table.
However, they came out with fine performances starting with their 2-0 blanking of world no. 10 Austria during their tournament opener on June 14 to earn the first and only victory so far in the group.
After that, they encountered another surprise team, Iceland, in the second round last Saturday and had settled to a 1-1 draw at the Stade Vélodrome in Marseille.
Head coach Bernd Storck's boys were actually fortunate to pull off a stalemate as the equalizing goal came from their opponents themselves, an own goal by Iceland defender Birkir Már Saevarsson at the 88th minute, after Swansea City midfielder Gylfi Sigurdsson scored the first goal on a penalty six minutes before the halftime break.
Meanwhile, Portugal is still winless after two rounds of matches with team captain Cristiano Ronaldo not being able to live up to expectations so far.
A Selecção has only scored once in their first two games, courtesy of Fenerbahçe striker and vice-captain Nani, but their defense remains solid conceding only one goal as well.
Manager Fernando Santos's squad is coming off a 0-0 stalemate with Austria also last Saturday at the Parc des Princes in Paris for their second round encounter, via ESPN.
Ronaldo had a chance to score the winning goal at the 79th when he stepped up to take a penalty kick, but his shot hit the post and bounced away to preserve the draw.
At the moment Iceland leads Portugal in goals scored, which puts them in the second spot of the group table with the latter at the third spot.
If both third round Group F matches ends up in a draw, Ronaldo and his boys must have a higher goals scored tally than Iceland to overtake them for second place or else both teams' fair play records will be the basis of the standings.
