The versatile 19-year-old defender departed Old Trafford for Glasgow last night, and managed to beat the midnight transfer deadline to sign a four-year deal at Celtic Park.
O’Connor failed to make any competitive appearances for United’s first-team but he seems to have been one of the Red Devils’ highest-rated young players, having been a regular standout for the Under-23s.
