Gers check out Boumsong's brothers
Boumsong is set to arrive at Rangers in the summer from Auxerre after agreeing a pre-contract with the Glasgow giants in January.
Yannick and Isaac Boumsong are currently undergoing a short trial at Rangers as they look to join their famous brother in Scotland.
The young duo watched Monday's Under-21 Old Firm game with Celtic and they are set to spend the next four days training with the first-team squad.
Gers boss Alex McLeish is looking to reshape his squad after a disappointing season and he will look at the pair before deciding whether or not to follow up his interest.
Should they decide to buy Boumsong's younger brothers it would help the French international settle into life at Ibrox easier.
