Primeira Liga misery continued on Sunday for Miguel Layun and company as FC Porto fell 2-1 to Arouca at the Estadio do Dragao.
Trouble started for Porto before the minute mark when Walter Gonzalez was able to beat his defender at the six-yard box and fire home after only ten seconds.
However, in the 14th minute, a Miguel Layun corner ended with Vincent Aboubakar heading past Rafael Bracali to level things at 1-1. The assist was Layun's 17th since joining the Portuguese side from Watford over the summer.
In all, it was a night to forget for Porto.
