Rangers are looking to strengthen their forward line after Youssef Chermiti suffered a long-term anterior cruciate ligament injury, while manager Derek McInnes has also warned that injuries have left his defence short of options. The setback is significant because Chermiti had been expected to play an important role this season and Rangers are preparing for a crucial Europa League qualifier against Jagiellonia Bialystok.

Chermiti, 22, was injured in Saturday’s defeat by Hibernian and may undergo surgery next week after seeing a London specialist; Rangers had recently rejected an unspecified bid for him. Left-back Tuur Rommens is out for up to eight weeks with a groin injury, prompting renewed interest in a left-footed defender, wingers and a striker; Brentford’s Jayden Meghoma and PSV Eindhoven’s Couhaib Driouech have been linked.
