Porto opened the scoring after 54 minutes through a bicycle kick from Brazilian striker Adriano.

With Porto's new coach Jesualdo Ferreira in the stands and caretaker Rui Barros on the bench, the champions doubled the lead after 75 minutes when Brazilian teenager Anderson tapped in.

One minute from the final whistle substitute Vieirinha completed the route with a powerful shot from outside the area.

Ferreira, Porto's sixth coach since they won the Champions League in 2004 under Jose Mourinho, replaced Dutchman Co Adriaanse who resigned last week after steering the club to the double.

Porto begin the defence of the league title at Uniao Leiria on Friday.
