Kris Commons, Celtic
Linked with: Crystal Palace, Leicester City.

Linked with: QPR.
This striker is an old favourite of Hoops manager Harry Redknapp and having failed to truly settle in Canada the 32-year-old could well be tempted by a reunion with him in West London.
Nicolas Gaitan, Benfica

Regarded as one of the most promising English players in the game this 19-year-old has been strongly linked with the Reds for some time.
Robbie Keane, LA Galaxy
Linked with: QPR.
A well known figure in English football this veteran forward could be tempted by a return with a switch to Loftus Road after winning three MLS Cups during his time in the USA.
