Martin O'Neill labels last season a "wake‑up call" for Celtic, warning that rivals Rangers and Hearts will challenge a title defence. The 74‑year‑old, now on a one‑year permanent deal, admits the squad lacks depth and the club has yet to secure a single signing while rivals rebuild.

Pre‑season began only weeks after O'Neill’s appointment, with backroom staff confirmed on the same day players reported. The coaching team is thin after Gavin Strachan’s departure, leaving O'Neill to rely on familiar faces Fotheringham and Maloney. The delayed staffing and absence of new arrivals raise concerns about preparation for a grueling schedule.

O'Neill stresses that reaching the Champions League group stage is vital, citing the previous season’s early exit as a catalyst for disappointment. He promises a blend of classic, direct football with modern possession, aiming to fine‑tune tactics during the extended pre‑season. Celtic must act swiftly or risk losing momentum before the opening league match.
