Vitória Guimarães beat Benfica at the Dom Afonso Henriques Stadium on Monday night to blow the Portuguese title race wide open.
Benfica went into the match still unbeaten in the Liga ZON Sagres, but the Eagles were never at their fluid best against a determined Guimarães side.
Brazilian striker Toscano scored what proved to be the winner shortly before the interval as Benfica's defense failed to deal with a free-kick.
The hosts continued their excellent recent form to hold on for the three points and become the first side to get the better Jorge Jesus' men in the league this season.
The defeat sees Benfica's lead at the top of the table cut to just two points. FC Porto are now within striking distance of the Lisbon club, and the great rivals meet in two weeks' time at the Estádio da Luz in a match that will surely have a crucial bearing on who become champions in 2011/12.
