Two goals late in the first half have given Porto breathing space in their Champions League Group G game with Maccabi Tel Aviv as the hosts lead 2-0.
Vincent Aboubakar could have given Porto a fifth-minute lead, but the forward nodded a free header at the far post straight into the arms of Predrag Rajkovic.
The Porto forward continued to find space inside the area as he sent another effort at Rajkovic before poking a left-footed attempt wide of the near post on the stretch.
He finally grabbed the opening goal as he again found space inside the area to thump home a header at the far post.
Just a few minutes later Yacine Brahimi made it 2-0 with a composed finish after being found on the break by Aboubakar.
