Former Swansea City loanee Jonathan De Guzman has joined Napoli from Villareal
Midfielder, 26, "can't wait to start in Italy"
Napoli have confirmed the signing of Dutch midfielder Jonathan De Guzman from Villareal.
The 26-year-old has spent the last two seasons on loan at Swansea City, playing almost 100 matches and scoring 15 goals for the Welsh club in all competitions.
Having completed a medical in Italy, De Guzman said: "I am happy to have come to Napoli. I can't wait to start."
The club also announced that Swansea have signed their Argentine defender Federico Fernandez, 27, for around £8m.
De Guzman only played half a season for Villareal before arriving at Swansea. The Dutch midfielder was part of the Netherlands squad that reached the semi-final of the World Cup.
He started the opening two group games before losing his place - he failed to feature again until the third-place play-off match.
Swansea were keen to bring him back to the Liberty Stadium but Garry Monk is reported to have grown frustrated by De Guzman's unwillingness to commit to the club before the tournament in Brazil.
De Guzman will join former team-mate Michu in Serie A.
