Porto is now on 3rd place. This season they have at home stadium 4 W, 1 D and 0 L. They have 2 victories in a row at home stadium, they are sure value at home ground. Porto have great players: Martinez, Quaresma, Danilo, Maicon, Alex Sandro, they are great team.
Rio Ave is now on 8th place. This season they have in away games 1 victory, 2 draw and 3 lost so far.
I expect Porto to lead on half time and to win easy on end of game.
