Shaun Maloney Reveals His Thoughts After Celtics Win Against Kilmarnock: Are There Any Flaws?Celtic blew Kilmarnock away at Rugby Park on Sunday, hammering Neil McCanns side 5-1 to make it two wins from two.Celtics 11m signing steals the show in ruthless Kilmarnock routThe headline act was obvious. Kasper Hgh scored a superb first-half hat-trick in another eye-catching display from Celtics record 11m signing. Benjamin Nygren and Luke McCowan then added to the damage after the break, while Michael Schjnning-Larsen grabbed Kilmarnocks only goal in the 56th minute.With Martin ONeill recovering from a minor hospital procedure, Shaun Maloney led the side from the touchline. Afterwards, the acting boss sounded delighted with what he had seen, particularly the way Celtic attacked from the opening whistle and refused to ease off.Im delighted. Really, really happy. He said. I thought we were excellent today.Id say the most impressive thing was the mentality. We started the game at full throttle, and we never came off it.Considering the week that weve had, its a massive credit to the group that theyve performed like that, and Im sure the boss is extremely happy.If he turned up on Monday and this hadnt been the result, I might have been in a spot of bother!Im really looking forward to having him back. Weve missed him today, and Im really glad we got a win for him.Hgh has wasted little time making his mark. The 25-year-old arrived after scoring 20 league goals for Bod/Glimt during the 2025/26 season, and his three-goal burst at Rugby Park showed exactly why Celtic spent 11m on him.T4O take: Celtic still gave Kilmarnock too much encouragementGLASGOW, SCOTLAND OCTOBER 29: Celtic Assistant manager Shaun Maloney is seen during the Premier League match between Celtic and Falkirk at Celtic Park on October 29, 2025 in Glasgow, Scotland. (Photo by Ian MacNicol/Getty Images)Yet the scoreline shouldnt shut down the debate around Celtics defending.Kilmarnock found their way through far too easily for Schjnning-Larsens goal, continuing a frustrating habit of giving opponents cheap encouragement. Celtic controlled huge periods, but Cameron Carter-Vickers and Auston Trusty still looked exposed whenever Kilmarnock sent direct balls beyond the midfield. That will worry the coaching staff.European opponents wont need many invitations. Celtic can dominate Scottish matches while still leaving gaps that sharper Champions League sides would punish without hesitation. Alistair Johnstons withdrawal at half-time added another issue. Celtic looked less secure after he went off, which again puts the spotlight on the depth behind the first-choice defenders.Arne Engels brought plenty of quality, although Celtic lost the ball too often in awkward areas and conceded needless fouls. Those moments disrupted their rhythm.Celtic must tighten up despite another huge winOut wide, Yang Hyun-jun and Camilo Durn produced flashes of quality, but both occasionally chose the wrong final pass or held the ball too long. Hgh found himself waiting for service during parts of the second half.Still, Celtic scored five away from home, and their 11m striker had the match sewn up before half-time. The warning signs remain, though. Five goals looked brilliant. The defending for Kilmarnocks one didnt.
