The Portuguese press have called for Cristiano Ronaldo to be dropped from the starting XI for Tuesday night's game against Spain.
Portugal will reach the finals of the Nations League if they avoid defeat to Spain in Braga. If Spain win, they will qualify instead. The Netherlands, Croatia and Italy have already booked their spot at next summer's finals - the third edition of the four-team tournament.
Ronaldo, 37, is Portugal's skipper but has struggled for form this season. The five-time Ballon d'Or winner has played a supporting role at Manchester United this season - starting just once in the Premier League - and has scored only one goal in all competitions.
