Barnsley, Portsmouth, Derby County and Charlton Athletic stars feature among League One's most valuable players after January transfers - gallery

League One is a division stacked with talent, with Barnsley, Portsmouth and Derby County stars among those who regularly impress.

However, in the modern game, how much money a player can command in the transfer market is arguably just as important as on-pitch contributions.

Gone are the days when hefty fees and high-profile moves were only seen in the Premier League. Now, there are plenty of ambitious EFL outfits willing to invest significantly in the pursuit of promotion.

An array of new faces arrived in League One during the January transfer window, including a string of players boasting impressive pedigree. A senior USA international joined Barnsley, while Bolton Wanderers landed a highly-rated defender on loan from Liverpool.

But who is the division’s most valuable player? With the transfer window now closed, The Yorkshire Post has taken a look at Transfermarkt data to generate a ranking of League One’s most valuable players.
