Although regular transfers and loans can no longer be arranged, clubs are still permitted to add unattached players to their squads.
The free agent market can prove risky and some managers prefer to steer clear of it. There are often concerns over fitness and match sharpness, particularly if a player has been on the shelf for a lengthy period of time.
However, various clubs have made shrewd signings following the closure of the window in recent years. There is no fee required to sign these players, meaning they can be low-risk additions.
A wide range of players are currently available, with seasoned veterans and promising up-and-comers among those who can be picked up.
Here is a look at 17 free agents EFL clubs could target following the closure of the transfer window.
