The January window is often a frantic time of of year for clubs to complete transfer business. Celtic and Rangers will both have one eye firmly locked on the future and the likely changes to their respective squads.
Hoops manager Brendan Rodgers and opposite number Philippe Clement will be looking to move certain players on this month and replace them with added quality, which is always a difficult challenge midway through a season.
Rodgers spoke of his failed pursuit to land former West Ham United captain Declan Rice during his first spell at Parkhead earlier this week as he outlined the difficulty of completing deals in this window.
A number of top players from across Europe and further afield are set to become free agents in the summer as they enter the final six months of their contracts. Here, GlasgowWorld looks at 14 players that both Glasgow giants could target with a view to next season and beyond:
