Former footballer Chris Sutton says Celtic may need to spend more than £50m on a summer overhaul to keep winning in the Scottish Premiership and to be competitive in the Champions League. Sutton’s comments, reported by multiple outlets, frame the potential spending as necessary to strengthen the squad for two simultaneous demands: defending their domestic title and meeting higher standards in Europe. The reporting does not provide detailed breakdowns of specific transfers or positions, but it links the projected budget to the scale of reinforcements Sutton believes are required. The outlets present the view as an assessment rather than a confirmed plan, emphasizing that the figure is conditional and linked to Celtic’s performance and ambitions. Overall, the articles agree on Sutton as the source of the £50m-plus estimate and on the stated rationale—maintaining competitiveness at both league and Champions League level during the coming transfer window.
