Celtic faced a 3-0 defeat to Rangers in the Premier Sports Cup quarter-final, a result that has raised questions about manager Martin O'Neill's choices in team selection and player performance. The match saw Sebastian Tounekti start for Celtic despite not being in the team for a period, marking only his second start of the season. His performance was heavily criticized, with former Celtic goalkeeper Pat Bonner calling it "awful" and pointing out that Tounekti lost possession 23 times during the game. He was substituted at half-time and replaced by Haissem Hassan, who joined the club from Real Oviedo in a deal worth up to £9 million. Bonner argued that Hassan should have started instead of Tounekti. Tounekti's inclusion was not the only attacking issue for O'Neill. Camilo Duran, who had been performing well in central positions, was moved to the middle, while Kasper Hogh, another high-profile summer signing, had returned from injury but was criticized for his performance. Former Rangers player Andy Halliday described Hogh as "absolutely freezing" and noted his lack of defensive effort. Hogh was substituted on the 64th minute, and Duran was also replaced 13 minutes later, indicating concerns about the effectiveness of the attacking trio. Defensively, O'Neill made changes by splitting up the center-back pairing of Cameron Carter-Vickers and Auston Trusty, who had started seven of Celtic's nine games this season. Kieran Tierney returned to the left-back position, and Liam Scales moved inside to partner Carter-Vickers. In goal, on-loan Wolves goalkeeper Sam Johstone was chosen over Viljami Sinisalo, who had performed strongly this season with four clean sheets in eight games. Johstone, making his second competitive appearance since March, looked rusty, and Rangers had clear chances early in the match. After the game, O'Neill admitted the need to review his team selection, saying, "I'll think about my own part in proceedings first of all and then we'll see." Fans were vocal in their criticism, with many arguing that Sinisalo should have started in goal and that Hassan should have been chosen over Tounekti. Others highlighted the lack of impact from Hogh and Duran and called for a re-evaluation of the team's strategy and potential January signings.
