Central defender Vitorino Hilton has signed a one-year contract extension with Montpellier.
AC Milan have completed the permanent signing of defender Cristian Zapata from Villarreal for an undisclosed fee.
Tottenham's highly-rated young defender Steve Caulker insists that he is open to the possibility of returning to Swansea next season.
The England Under-21 international played a major role in helping Swansea secure an 11th place finish in their first season in the Premier League.
The 20-year-old has now returned to White Hart Lane, but faces tough competition for places in Tottenham's defence next season.
Having made 26 starts in total for Swansea this season, the composed centre-half believes that he needs to be playing regularly next term to continue his development.
"I've loved every minute of my time at Swansea since going over there during pre-season," Caulker told Sky Sports.
"I spent around nine months at the club and I learned things every day, with the gaffer giving all the lads bundles of confidence.
"A big part of my game now is composure and I've managed to add that to my game this year whilst at Swansea.
"The main aim for me is to continue my development and the only way I can see that happening is by playing regularly.
"I'm sure that over the summer I'll sit down and decide what is best for me, but I can't emphasise enough how important it is for me to be playing.
"I've still got a lot to learn and I've learned so much in a year here at Swansea that should it be available again to me next season and Tottenham are happy with it I'd be stupid to say no."
Many top-flight newcomers struggle during their second campaign, but Caulker expects Swansea to repeat their stunning success story next term.
He added: "I'm confident that they will do just as well next season because as the season has gone on we seem to have got stronger.
"Our first game of the season was away at Manchester City and we lost 4-0, but in the return leg we managed to beat them 1-0, which is a sign of how far we have come and how much we've learned throughout the season."
