Cousin should finally discover this week whether the £3million transfer can be completed even though he has already played for both Lens and Rangers this season.
In the meantime, he was drafted into the starting line-up for the first time since last month's win against Inverness and bagged the opener as Rangers earned a 4-2 win over Gretna in the Clydesdale Bank Premier League.
"He popped up with the opening goal today and got us on our way. There hasn't been much change in him.
"He showed today that he still loves the club and his reaction when he scored was great. Hopefully everybody will get behind him while he is still a Rangers player."
