Cristiano Ronaldo scored Portugal's 50th goal at the World Cup after netting in the Group H opener against Ghana.
The 37-year-old scored from the spot after a controversial penalty was awarded Portugal by referee Ismail Elfath.
Portugal had not been at the World Cup in the first seven editions from 1930 to 962 but made their debut at the 1966 tournament.
José Augusto scored Portugal's first-ever goal at the World Cup in a 3-1 win against Hungary and in that same tournament Eusebio became the highest top scorer with 9 goals. A record that is yet to be broken.
Portugal's last goal at the World Cup before Ronaldo's opener against Ghana was scored by Pepe in the 2-1 defeat to Uruguay.
Ronaldo has now scored eight goals in 5 tournaments and on his 18th World Cup match.
