Sanogo has scored just once for the Gunners since arriving from Auxerre 18 months ago, but Bruce is an admirer of the powerful young forward.
He said: "I don't know how many starts he's had but he played against us in the cup final and I was very impressed with him. I saw him play for Arsenal against Dortmund in the Champions League as well.
"For the French under-21s he's been nothing short of fantastic. I saw a game when they beat England and I thought he was terrific.
"When you take a young boy, especially a striker, it's a question of whether they can come and do it. I took Nicklas Bendtner when he was 18 (to Birmingham) and he won me the Championship."
