Andy Walker believes the loss of Joe Aribo and Calvin Bassey could result in Rangers missing out on the Champions League.
The former Light Blues duo departed the club earlier this summer in big money moves to the English Premier League with Southampton and to the Eredivisie to join Ajax. Both played major key roles in the Europa League run to Seville last season with Giovanni van Bronckhorst's men losing in heartbreaking circumstances to Frankfurt.
Rangers travel to the Netherlands next week for their play-off return after a 2-2 home draw with PSV on Tuesday night - setting up a nervy 90 minutes with the winner landing a spot in the lucrative group stages of the Champions League. During their European run last season the Ibrox men defeated the likes of Borussia Dortmund and RB Leipzig, with ex- Celtic man Walker admitting they are more than capable of going away and getting a big result.
