The former Netherlands under-21 international worked with new Swans boss Michael Laudrup at Mallorca, and after Villarreal’s relegation from La Liga the Spanish club are keen to lower their wage bill.
De Guzman joins Jose Manuel Flores, who moved from Genoa, as the Liberty Stadium club’s new additions, and is eager to get started in the Premier League.
“Once the opportunity came along to join Swansea and Michael Laudrup it was a done deal. I didn’t have to think twice about it,” he confessed to the side’s official website.
“I watched Premier League football every week on the TV last season. I was aware that Swansea are a good footballing side, but they really caught my eye when they beat Manchester City. They had a great season and I am really looking forward to the challenge of playing on a new (stage) in the Premier League.
“I’m grateful for the opportunity and grateful that the manager has acknowledged me as a player,” he concluded.
