Allan highlighted Iheanacho's late winner against Dundee as evidence of his superior finishing compared to Tomas Cvancara. The forward, who has battled injuries, is described as the most instinctive and clinical option available to Celtic.
"If you can keep Iheanacho fit, that's the million dollar question," Allan told the BBC's Scottish Football Podcast. He argued that while Cvancara is a stop-gap, Iheanacho's ability to link play and his killer instinct make him the ideal first choice for the title push.
