Last Saturday, Salvador Sobral was crowned the victor of the 2017 Eurovision Song Contest in the host city of Kyiv, bringing his country their first Eurovision victory since their debut in 1964.
The 27-year-old Sobral was a virtual unknown before his triumph in Kiev, but around 2,000 jubilant fans cheered his arrival at Lisbon's airport.
"If I can help to bring some change to music, I will be really joyful". He won with a non English song titled Amar Pelos Dois.
Unlike the 25 other competitors who performed on a wide stage backed by flashing lights, bursts of flames and other effects, Sobral sang from a small elevated circle in the middle of the crowd, an intimate contrast to others' bombast.
It has been only a matter of days since Salvador Sobral won for Portugal with a record number of points.

With the capacity at 20,000, these figures make it seem a ideal venue to host the Eurovision Song Contest in Lisbon.
While accepting the award, Sobral said, "Music is not fireworks, music is feeling".
"We aren't the only winners this evening.!" Bulgaria came in second place with 615 points and Moldova came in third with 374 points.
Ukrainian President Petro Poroshenko on Saturday cancelled his planned appearance at the Eurovision Song Contest final in Kiev after a shelling attack in the war-torn east reportedly killed four civilians.
He said on receiving the trophy: "We live in a world of fast food music". The song is entirely in Portuguese. The union, however, was criticised for not banning 1944 past year, allowing Russia-Ukraine tensions to fester.
Past year its contestant Jamala won with a song called "1944", referring to the Stalin-era deportation of her Crimean Tatar ethnic group from the Black Sea peninsula. This year's contestant however, Yuliya Samoylova, was banned from competing by Ukraine because she had toured in Crimea after Russia's 2014 annexation of the peninsula.
