Arouca stunned the Portuguese giants on Sunday by opening the scoring almost instantly at the Estadio do Dragao, with Walter Gonzalez setting them on their way to a 2-1 win
It's vital, the experts always say, to start strongly. Stamp your authority on the game early on so that you can take control. Porto, it seems, have some work to do on this front.
The Portuguese giants suffered an immediate setback on Sunday as they allowed mid-table Arouca to score after just 11 seconds of their Primeira Liga meeting, Walter Gonzalez bundling the ball over the line as Iker Casillas and his defenders struggled to comprehend what was happening around them.
Vincent Aboubakar equalised for Porto 13 minutes later but it would appear that the damage was already done as a galvanised Arouca hit back for the win in the second half, Gonzalez scoring his second.
It leaves Porto stuck in third in the table, six points behind leaders Benfica - who will host Jose Peseiro's side in their next game. They can't afford to do this at the Estadio da Luz!
