Cristiano Ronaldo became the European Championship's all-time leading scorer when he grabbed the winner in the Euro 2016 qualifying victory over Armenia.
The Real Madrid forward scored his 23rd goal in European qualifiers and finals when he scrambled home in the 71st minute after Portugal had struggled.
That took him past Denmark's Jon Dahl Tomasson and Turkey's Hakan Sukur, both of whom scored 22.
Portugal moved into second in Group I with six points from three games.
Apart from his goal, world player of the year Ronaldo had a poor game, highlighted when he fired three free-kicks into the Armenia wall.
Armenia had chances, with Borussia Dortmund's Henrikh Mkhitaryan forcing Rui Patricio into a great save in the 14th minute.
Midfielder Kamo Hovhannisyan also tested the Portugal goalkeeper in the opening half-hour.
Former Chelsea full-back Jose Bosingwa, 32, made his Portugal return after a four-year absence, while another ex-Blues player, 36-year-old Ricardo Carvalho, also started.
Germany 4 Gibraltar 0
Germany manager Joachim Low was critical of his side despite a comfortable win over minnows Gibraltar.
The 4-0 victory lifted the world champions, who had lost and drawn their previous two games, from third to second place, level on points with Scotland and the Republic of Ireland.
Low said: "I am everything but satisfied with this. The team did not do what we wanted to do.
"We wanted to play as world champions and four goals are too few."
Thomas Muller scored twice before Mario Gotze and a Yogan Santos own goal sealed a comfortable win in Nuremberg.
Former Portsmouth midfielder Liam Walker went close for the visitors with a dipping shot from 35 yards.
Gibraltar, Uefa's newest member nation, have lost all four qualifiers and conceded 21 goals without scoring but coach Allen Bula was delighted with his team.
He said: "It's a great result and we really needed something like this - 0-4, I could not have asked for more."
