Leeds United chose not to bring in any senior players during the January transfer window despite their intent to pursue Brenden Aaronson.
The Whites identified the hard-working 21-year-old as a primary attacking midfield target but could not tempt Austrian champions FC Red Bull Salzburg into parting with the player.
Leeds lodged two bids - totalling £15 million and £20 million - with the Austrian club, but neither were accepted, at which point Leeds opted against a third approach.
