Ange Postecoglou is facing the worst injury crisis of his coaching career "by a fair stretch" after losing centre-backs Cristian Romero and Micky van de Ven to new muscle injuries against Chelsea on Sunday.
Postecoglou will be without nine first-team players for Thursday's Europa League game against Rangers here in Glasgow, with Ben Davies, Richarlison, Wilson Odobert (all hamstring) and Guglielmo Vicario (foot) also sidelined, Djed Spence and Sergio Reguilon ineligible and Mikey Moore still recovering from illness.
