LISBON, Portugal (AP) FC Porto squandered a two-goal lead in a 3-2 home loss to Guimaraes on Saturday, while Benfica needed a late goal by 18-year-old Joao Felix to draw 1-1 with Sporting Lisbon in the Portuguese capital derby.
Defending champion Porto appeared to have the game well in hand after Yacine Brahimi and Andre Pereira both scored before halftime.
But Andre Andre converted a penalty in the 63rd minute and substitute Antonio Carvalho leveled in the 76th.
Substitute Davidson completed the comeback for the visitors with a goal in the 88th, dealing Porto its first loss in three rounds this season.
“We are not doing the things that made us champion,” said Porto coach Sergio Conceicao. “We need to talk.”
Porto’s second goal was scored with Pereira in an off-side position, but the video assistant referee apparently did not advise the referee due to a technical malfunction in the communication system.
“There needs to be an alternative to communicate,” Guimaraes coach Luis Castro said. “If the VAR goes down, there must be another option. A team could be hurt by this.”
In Lisbon, Joao Felix jumped to head in a cross from Rafa Silva to score for Benfica in the 86th minute, cancelling out a penalty converted by Sporting’s Nani in the 64th.
Goalkeeper Romain Salin made several saves to keep Sporting ahead until Felix finally got a ball past him.
