Lisbon, Portugal (SportsNetwork.com) - FC Porto interim manager Luis Castro sustained his first defeat in charge of the club as Islam Slimani's 52nd- minute goal was enough to give Sporting Lisbon a 1-0 win over the defending champions.
Castro took over for Paulo Fonseca earlier this month, and after beating Arouca in league play and Napoli in the Europa League, the manager tasted defeat as Porto's boss for the first time.
The difference in the match came when Slimani shook free from his defender to head home a right-wing cross from Andre Martins at the far post, dooming Porto to a fifth defeat in league play and leaving the club 12 points behind leaders Benfica.
Sporting's victory moves the club five points beyond Porto in second place, while the team remains seven points adrift of Benfica after the club's 4-2 win at Nacional on Monday.
Benfica built a 3-1 lead at halftime but saw its advantage cut in half when Djaniny scored 10 minutes from time for Nacional. But Ezequiel Garay scored his second goal of the contest for the visitors in the 89th to seal the win.
Rio Ave claimed a 2-1 win at Gil Vicente when Andre Ukra converted a penalty kick in the 89th minute to break a 1-1 deadlock, while Pacos Ferreira moved off the bottom of the table after notching a 2-1 win over Guimaraes through goals from Bebe and Sergio Oliveira, whose tally came six minutes from time to secure the win.
Joao Pedro's goal in the 11th minute was enough to help Estoril to a 1-0 victory over Maritimo, Academica and Braga traded first-half goals in a 1-1 draw, Rafael Martins netted two goals in a 3-1 Setubal win at Belenenses and Arouca topped Olhanense, 2-0, with successful penalty kicks from Roberto Rodrigo and Lassad Nouioui.
