[5] O'Connor had trials at Crystal Palace and Leicester City,[6] then another with Leeds United in March 2017, where he impressed then-coach Garry Monk enough to secure a 2+1⁄2-year contract for an undisclosed fee from Limerick.

After his signing the contract, director of football Victor Orta said of O'Connor, "he will be a key player for Leeds United for many years to come", and that the club intended to send him out on loan for regular games.

O'Connor scored his second goal of the season, on 31 October, in a 2–1 defeat to Premier League side Arsenal in the Carabao Cup at the Emirates Stadium.
