Milan coach Stefano Pioli complained about Porto’s goal with referee Felix Brych after the Rossoneri’s 1-0 loss in Portugal.
Milan have three defeats from their opening three Champions League games.
A Luis Dias goal gave Porto all three points at the Estadio Do Dragao, but Milan players complained as Taremi collided with Ismael Bennacer on the edge of the box just before Dias scored the eventual winner.
Even Stefano Pioli could not hide his disappointment.
Before entering the tunnel, he stopped to talk to referee Felix Brych, clearly telling him ‘It was foul, it was foul.’
This season, the Rossoneri are not quite lucky with referees in Champions League. Turkish official Cüneyt Çakır conceded a controversial late penalty kick to Atletico Madrid last month, leading to Milan’s 2-1 defeat.
The Rossoneri need to win the next three group stage games to keep their qualification hopes alive.
They host Porto at San Siro on November 3 before visiting Atletico Madrid on November 24.
They play the last group stage game at home against Liverpool on December 7.
