Giovanni van Bronckhorst insists Rangers still have work to do in their Europa League last-16 tie following their thrilling 3-0 win over Red Star Belgrade at Ibrox.
Gers skipper James Tavernier slotted in a VAR-awarded penalty in the 11th minute and striker Alfredo Morelos doubled that lead with a driven shot four minutes later before Light Blues goalkeeper Allan McGregor brilliantly saved a Aleksandar Katai penalty.
Katai had put the ball in the net twice in the first half, only to be thwarted by the offside flag, as was substitute El Fardou Ben Nabouhane when he slid the ball in near the end, while the visitors also hit the bar with a shot from Guelor Kanga.
