The winter transfer window.
For most fans, this period brings excitement and intrigue as they sift through rumors about who their team is targeting or likely to sign.
As with the summer window, this is a chance for teams to strengthen their squads in order to better compete domestically.
While fans of most leagues look forward to this time, La Liga fans certainly do not, at least not lately.
Over the past few seasons, the transfer window has simply been a time where the best talents in Spain outside of Real Madrid and Barcelona have been forced to leave for financial reasons.
The list of top class, even world class talents that have left Spain in recent seasons frustrates fans everywhere.
Santi Cazorla, Javi Martinez, Juan Mata, David Silva, Sergio Aguero, etc. The list of names is too great to put here.
While the winter window usually means fewer moves and while the new Financial Fair Play rules are predicted to encourage less frequent and less expensive signings, Spain's first division is still likely to lose a few stars.
Some players may move on to other leagues while others could simply move to better Spanish teams. Some are likely to move in January while, for others, a deal to move next summer could be in order.
What follows are three players who, for very different reasons, have a high chance of being on the move this winter. Please read on to see exactly who these players are.
