Leeds United were unable to bolster Marcelo Bielsa's first-team squad during last month's transfer window, although attempts were made to add an attacking midfielder.
Two bids, reported to be in the region of £15 million and £20 million, were rebuffed by Austrian side FC Red Bull Salzburg as USMNT international Brenden Aaronson was identified as Leeds' primary target.
The Whites were unwilling to lodge bids for any other player, preferring to go all in on their chosen man, however extenuating circumstances meant Leeds were unable to land the 21-year-old.
