Didier Drogba hints he may follow Frank Lampard and Steven Gerrard by ending his career in the United States.
Southampton's on-loan defender Toby Alderweireld hopes his future can be resolved quickly.
Chris Samba has left QPR to rejoin Anzhi Makhachkala for a "club record undisclosed fee".
Rangers made Samba their record signing in January, but the centre-half was unable to prevent relegation to the Championship.
Samba's form at Loftus Road fluctuated, and at one stage he became embroiled in a Twitter row with supporters questioning his wages.
But Anzhi have not been put off re-signing the 29-year-old, who spent a year in Russia before his move to London.
A statement on the QPR website read: "The club would like to wish Chris all the best for the future and thank him for his contribution to QPR."
