Celtic are prioritizing moves for a central midfielder, winger, and a backup left back before the window closes, as manager Martin O'Neill looks to add quality and strength in depth to his squad. The Hoops' squad, as things stand, is lacking the depth required to compete for silverware domestically and in Europe, despite the season having already started. League standing (final 2025 table -- new season not yet under way): 3rd in Premiership, 67 pts, 21W-4D-8L from 33 games, recent form WWWWW. Goals this season: 59 scored, 35 conceded (+24 goal difference). Title race: 3 points behind leaders Heart Of Midlothian. Last result: Celtic 3-1 Heart Of Midlothian (2026-05-16). Recent form (last 5): 5W-0D-0L (WWWWW, most recent first); on a 5-game winning run. Currently sidelined: Jota. According to sources, Celtic are in the market for a new midfielder, another winger, and left-back cover for Kieran Tierney. Martin O'Neill wants to add more depth to his squad as well as quality players in those positions as we enter the final month of the transfer window. The priority for Celtic and Martin O'Neill would be to bring in a new midfielder, another winger and left back cover for Kieran Tierney as well. Speaking on the Transfer Insider podcast, I explained: "Celtic are in the market for a new goalkeeper, but that isn't one of their priorities at this stage of the window. The good news, then, is Football Insider revealed in May that Celtic are prepared to leave their business until the latter stages of the window rather than rushing into deals. O'Neill's side will face a two-legged playoff against LASK as they aim for qualification to the Champions League, and reaching the group stages could boost their plans. They fell at the same hurdle last August against minnows Kairat Almaty, but will fancy their chances of progression to the league stage under a new manager this time around.
