Joao Felix takes a shot federation of nations Defending champions Portugal took a first-half lead against Wales in Lisbon.
The former Chelsea striker’s shot from 20 yards out deflected and hit Danny Ward.
Wales are on a four-game winless run under Craig Bellamy and are without a large number of players.
Experienced superstar Cristiano Ronaldo came close to scoring on a couple of chances in the half before his Al Nasr team-mate Felix broke the deadlock.
Left-back Nuno Mendes found space behind Ethan Ampadu and played the ball back to Felix, whose shot beat Wales captain Ben Davies and into the net.
Wales lost three of their four meetings with Portugal, apart from a friendly in May 1951 which they won 2-1 with goals from Mal Griffiths and Trevor Ford.
