Making the switch from Cork City to west London, O’Connor brings with him first team experience, having made 10 appearances across all competitions in the 2026/27 season for Cork City, who sat 20 points clear at the top of the Ireland first division when he made the switch.
At 6ft 1in, O’Connor is a commanding centre-half with invaluable game-time under his belt, providing Saunders’ side with serious stature at the back.
A proud Irishman, the defender cites Bees captain Nathan Collins as a big inspiration and played with Brentford and Ireland keeper Caoimhin Kelleher’s brother, Fiacre, at Cork.
