Portugal will host next summer's Nations League finals after they secured their passage from Group A3 thanks to a goalless draw against Italy.
Portugal, Italy and Poland were the only three countries that had bid to host the games in June 2019, so as Portugal clinched top spot they will now stage the climax of the inaugural competition.
Portugal secured their place in the Nations League finals after a 0-0 draw in Italy clinched top spot in Group A3.
Italy could not take their chances, with Ciro Immobile wasting their best opening in the first half.
The draw at San Siro means Portugal, who host relegated Poland on Tuesday, cannot be overtaken at the top of the group and will take part in next summer's finals, which they are set to host.
All three nations that bid to host June's finals were in Group A3, so Portugal's victory leaves them as the only candidate to stage the event, subject to formal appointment at a UEFA executive committee meeting on December 3.
Portugal boss Fernando Santos felt his side deserved the point in Italy which earned them qualification for the Nations League finals.
Santos' side were without Cristiano Ronaldo again but they got the job done at San Siro to finish top of Group A3 ahead of Italy and relegated Poland.
"It is a fair result because, from a moment in the second half, Portugal were better," Santos told a press conference after his side had struggled to contain Italy before the break.
"In the first, with the moves in the midfield, Italy managed to win many second balls.
"(Lorenzo) Insigne's movements inside created a lot of problems. (Joao) Cancelo did not always close the game well and that caused Ruben Neves to go too low, leaving Pizzi and William (Carvalho) in two-on-three situations.
"We realised what was happening and we improved, the suffocation was over. The game was balanced, we were growing and we managed to withdraw. We were forced to play behind the ball and we were improving."
