The Selecao's all-time top goalscorer endured a forgettable evening as Roberto Martinez's side drew level with a clean sheet.
Cristiano Ronaldo, for all these goals, accolades and magical moments, cannot be the main man every night. And against Portugal against Slovenia, his shortcomings were starkly exposed as his side turned in a disappointing performance that eventually lost 2-0.
Ronaldo was unengaged throughout and only managed one shot from open play.
After a sluggish first half, things opened up in the second half. Benjamin Cesko came close for Slovenia, making a fine save from Diogo Costa in the Portugal net, while Ronaldo also showed signs of life.
Adam Knesta provided Serin's crucial moment, however, with a brilliant run from central midfield to finish off a well-constructed goal for the hosts – good value for their lead. Portugal provided an answer, however, as Joao Felix pinged a header into the post.
Timi Elznic then doubled Slovenia's lead, volleying into the roof of the net from a tricky angle to put the match beyond doubt – and end an 11-game winning streak for Roberto Martinez's men.
