Darren Bent to Rangers - 3.8
After Kenny Miller ruptured his hamstring against Hibs, Rangers began the search for his replacement. Bent has been missing for Derby since the start of the season, but is working his way back to full fitness. Rangers have shown interest in signing the former England international.
Terence Kongolo to Huddersfield - 2.1
After arriving with a promising reputation from Feyenoord, the Dutch defender has failed to make an impact in Ligue 1 with Monaco.

A Chelsea transfer target in the summer, and after disagreements with Diego Simeone, Carrasco is looking for a new club and hasn't started a league game since October. Antonio Conte could move to add this exciting forward to his squad.
Karl Toko Ekambi to Burnley - 1.8
Playing for one of France's smaller clubs, the 25-year-old has impressed for Angers scoring nine times in 18 games, adding three assists. The Loire club are very good at selling when players are at their peak value. They will find it hard to say no if Burnley come calling for the forward in January.
