Portugal will begin their European Championship campaign against the Czech Republic on June 18, while Finland will return to competitive action at the start of September in the UEFA Nations League.
Match preview
England and France are viewed as the favourites to win Euro 2024, but Portugal are serious contenders, with a squad packed full of talent certainly capable of going all the way in Germany this summer.
Roberto Martinez's side breezed through their qualification group, winning all 10 of their matches in Group J, scoring 36 times and conceding just twice, with Cristiano Ronaldo netting 10 goals, and he is again set to be a vital player for his national side this summer.
Portugal won the European Championship in 2016, but they only reached the round of 16 at Euro 2020, so there is clear room for improvement in the upcoming competition, and it would be fair to say that the European giants are the heavy favourites to top Group F.
A Selecao das Quinas will begin their campaign against the Czech Republic on June 18 before tackling Turkey and Georgia in their final two fixtures in the section.
Portugal, who suffered a 2-0 loss to Slovakia in their last friendly at the end of March, will also face Croatia and the Republic of Ireland during their warm-up fixtures for Euro 2024.
Finland qualified for Euro 2020, with the national side competing in the finals of a major tournament for the first time in their history, but they were knocked out in the group stage.
The Eagle-Owls lost to Wales in the semi-finals of the playoffs for Euro 2024, so they will not be present in Germany, with their next competitive match coming in the UEFA Nations League against Greece at the start of September.
Markku Kanerva's side will also take on Scotland on June 7, and they are in strong form, winning three of their last four matches in all competitions, including a 2-1 success over Estonia last time out.
Finland have one victory over Portugal to their name, triumphing 4-1 in a friendly back in 2002, but they have lost their last two matches against Tuesday's opponents, including a 2-0 defeat when the two teams last locked horns in March 2011.
The Eagle-Owls certainly have the quality to make it a tricky match for Portugal, which is what Martinez will be looking for in preparation for what is shaping up to be a fascinating European Championship.
