The summer transfer window is now done and dusted, but second-tier sides are still able to snap up players who are currently out of contract, and there's a number of intriguing options still out there on the hunt for a new club.
From former England internationals to injury-plagued players looking for a fresh start, the free agent market is a varied, often risky business to be involved in. However, if a club strikes lucky, they can find themselves reaping the rewards when their new signing defies the odds and revives their career.
Here's a look at 15 free agents that Barnsley and all their divisional rivals could look to bring in - some more realistic than others, granted - now that the transfer window has closed:
1. Carlos Sanchez - CM
Is there every an end of transfer window run-down that doesn't contain the former Colombia international? The veteran midfielder is on the look-out for another club, after being released by Watford at the end of last season.

2. Gaetano Berardi - CB
Deemed surplus to Leeds United, the Swiss powerhouse could still do a job for a number of Championship sides - even if it is on a one-season basis. He made 22 appearances in the season that saw the Whites finally secure promotion back to the top tier.
3. Adrian Mariappa - CB
He's currently a free agent, but is still involved in World Cup 2022 qualifying with Jamaica. With over 220 Championship appearances, the 34-year-old knows the division well, and spent last season with Bristol City.

4. Salomon Kalou - ST
We saw ex-Chelsea ace John Obi Mikel play for Middlesbrough and Stoke City later on his career, so why shouldn't Kalou have a crack at the Championship? That said, he's probably going to join Portuguese side Os Belenenses instead.
