24-year-old winger Goncalo Borges has left Porto permanently to sign for Feyenoord in a deal said to be worth around €10 million.
The winger ends a long association with Porto, which began 10 years ago when he left Benfica's academy to join the Portistas.
He made 88 appearances for the Dragons in that time and scored two goals, both of which came last season in what was his best campaign yet, with him playing 38 games and getting six assists.
He'll most likely be replacing Igor Paixao at Robin van Persie's Feyenoord, with the Brazilian winger set to sign for Marseille.
