The 24-year-old midfielder is expected to leave Nottingham Forest this summer, with a host of Championship outfits interested in him.
Leeds want to add a midfielder to their squad and have been looking closely at signing O’Brien
Middlesbrough are also in the race for the Nottingham Forest midfielder’s signature.
Michael Carrick’s side have money in the bank with their recent sale of Chuba Akpom to Ajax and they are now pushing for the deal.
Leeds, despite their interest in O’Brien, are backing away and Boro are closing in on a loan capture.
Nottingham Forest sent out O’Brien on loan to DC United in the second half of the season where he impressed with his performances.
With three days remaining in the transfer window, it remains to be seen whether Leeds will be able to strengthen their midfield with alternative targets.
