Negotiations will also take into account players’ contracts at clubs, as some enter the final few months of their current deals.
That may allow clubs to sign players for a reduced fee, while some will be trying to agree new deals rather than losing assets on a free transfer.
According to Transfermarkt, here are the most valuable Championship players who are in the final year of their contracts.
It should be noted that some clubs have options to extend player's contracts - often by a further year.
