Andy Walker says Rangers need to learn how to do business as they look set to lose Ryan Kent and Alfredo Morelos for nothing.
The Sky Sports co-commentator reckons the Ibrox side could have banked upwards of £15m for Kent and similar for his Colombian teammate at their peak.
But the pair are set to end on a Light Blues whimper, with Michael Beale's side all but certainly ending this term without silverware and having been met with various levels of criticism throughout the campaign.
Neither are close to signing contract extensions and winger Kent is said to have 'agreed' a deal to join Fenerbahce. Rangers sold Calvin Bassey for a record fee in the last 12 months and made eight figures on Nathan Patterson's deal that sent him to Everton in January 22, but Walker reckons new business lessons are needed like those which have Celtic brimming with assets.
