All Celtic’s summer signings rated as only two earn pass marks and marquee buy scores 4/10

Ryan McDonald assesses Celtic's summer transfer business, arguing that only two new arrivals have earned pass marks while record signing Kasper Hogh has struggled. Despite spending approximately £35 million following Arne Engels' departure, Celtic suffered elimination from the Champions League and consecutive defeats against Rangers under manager Martin O'Neill.

McDonald highlights playmaker Mika Baur as a rare success following his £6.8 million move from Paderborn, whereas club-record £11 million signing Hogh has gone eight matches without a goal in his last nine outings. Late-window loan arrivals and injured prospects have so far failed to stabilize the squad.
