Zaidu Sanusi opened the scoring for Porto with his first Uefa Champions League goal in their 2-0 victory over Marseille on Wednesday.
The Nigeria left-back broke the deadlock in the 39th minute after pouncing on a rebound which came from a corner-kick.
Sanusi was in action for 90 minutes and he produced a man-of-the-match display as Porto sent Marseille packing from the Champions League.
The 23-year-old's strike at the Orange Velodrome was his goal for the Dragons since he completed a permanent switch from their league rivals Santa Clara in the summer.
