Zaidu Sanusi scored his first goal for FC Porto as they beat Marseille 2-0 Orange Velodrome to boost their chances of progressing to the last 16 of the Champions League.
The 23-year-old left back opened scoring for the visitors in the 39th minute and Sergio Oliveira added a second for the visitors in the second half.
Marco Grujic saw red for Porto for a second yellow card in the 67th minute and the hosts were also reduced to 10 men three minutes later after Leonardo Balerdi received his marching orders for a second bookable offence.
Sanusi who joined the Portuguese giants in the summer has started all four games in the Champions League this season and was on for the entirety of the match. He has made nine appearances in all competitions recording a goal and assist.
The victory leaves Porto second in Group C with nine points and needing just a point to progress to the knockout round while Marseille remain winless in last place.
Earlier, Group leaders Manchester City booked their place in the last 16 with a 1-0 win at Olympiakos who are third on three points.
Elsewhere, Super Eagles midfielder Frank Onyeka was on for the entire 90 minutes as FC Midtjylland remain without a win in the Champions League after they were thrashed 3-1 at Ajax in Group D.
The debutants held the hosts to a goalless first half but conceded thrice after the break with Ryan Gravenberch, Noussair Mazraoui and David Neres giving Ajax a 3-0 lead.
Midtjylland reduced the deficit after Awar Mabil scored a penalty to record just their second goal in the competition.
The much-needed win keeps Ajax in second place on seven points, level with Atalanta who shocked leaders Liverpool at Anfield in the group’s other game.
