Chelsea are well known for their use of the loan system, and it has been no different this season.
Despite facing a transfer ban over the summer window, the Blues still sent 27 players out on loan for at least the first half of the season.
The ones playing over Europe have had a quiet Christmas due to the winter break that takes place, but the ones staying in England had no such luck, with games coming thick and fast.
There is also the matter of the January transfer window, which has seen players linked with a move.
So, here is the latest on some of the players who have seen action over the new year.
Trevoh Chalobah
Played the full 90 minutes of Huddersfield's high scoring 5-2 loss against Stoke City on New Year's Day. The result leaves the Terriers in 20th place in the Championship table.
Matt Miazga
Came on as a second-half substitute in Reading 2-1 away win over Fulham, after going four league games without an appearance.
Richard Nartey
Has quickly established himself as a crucial player for Burton Albion, he played the full 90 minutes of the brewers' 4-3 win over Bolton Wanderers.
Conor Gallagher
Has caught the eye at Charlton this season, and was back in action on New Year's Eve, when he played the full 90 minutes of the 2-1 loss vs Derby County.
The Daily Mail report that the midfielder is likely to cut his season-long loan short and join Premier League side Burnley on another loan deal.
Luke Mccormick
Has returned to Stamford Bridge after failing to establish himself at Shrewsbury Town, making just seven first-team appearances.
Danny Drinkwater
