Wayne Routledge scored as Swansea rounded off their tour of Holland with a 1-0 victory over ADO Den Haag on Saturday.
The winger lifted the ball over home goalkeeper Gino Coutinho in the 21st minute after an assist from Jonjo Shelvey for the only goal of the pre-season friendly at the Kyocera Stadion.
New £12million signing Wilfried Bony made his first appearance in a Swans shirt, as Michael Laudrup made eight changes at half-time.
The former Vitesse striker went close on several occasions in the second half but could not mark his debut with a goal.
Having won all four of their friendlies in the Netherlands, Swansea return to pre-season action away to Yeovil next Friday.
