Iran Press/Europe: However, Mehdi Taremi's night ended in misery when he was sent-off in the 73rd minute for a poor challenge on Nicolas Otamendi.
Spanish defender Alex Grimaldo had put Benfica in front after just 17 minutes at the Estadio do Dragao, finishing off a fine pass from Haris Seferovic.
The lead lasted just eight minutes before 28-year-old striker Taremi brought Porto level with his seventh league goal of the season.
