Rangers are through to Friday's draw for the Europa League quarter-finals and semi-finals after knocking out Red Star Belgrade in the last 16.
Giovanni van Bronckhorst's side lost 2-1 on the night in Serbia but won 4-2 on aggregate thanks to a 3-0 victory in last week's first leg at Ibrox.
Red Star took an early lead in the return match through Mirko Ivanic and Allan McGregor made some vital saves before Ryan Kent equalised in 56 minutes.
Ben Nabouhane converted a stoppage-time penalty for the hosts but it is Rangers who can now look forward to the last-eight ties on April 7 & 14.
