Three things learned from Celtic’s defeat to Rangers, as Callum McGregor is no longer good enough

Celtic has suffered its second defeat to Rangers within a week, increasing the pressure on manager Martin O'Neill. The loss has highlighted several key issues for the club, including the performance of captain Callum McGregor, who is criticized as no longer being good enough to start regularly. Despite the defeat, Celtic remains at the top of the Scottish Premiership table.

Manager Martin O'Neill is also facing scrutiny over his handling of the goalkeeping situation, having rotated between Viljami Sinisalo and summer signing Sam Johnstone. Additionally, there are concerns regarding a lack of trust in other summer signings, including Haissem Hassan, Kasper Hogh, Alex Oxlade-Chamberlain, and Shim Mheuka, who were all named on the bench.
