Bassong worked with Redknapp at Tottenham.
He told Absolute Radio: "I'm sure he's going to do well [laughter] I know him very well and I know what he's capable of and I think he's going to bring QPR his magic and I hope for him he's going to do really well.
"I know, but he's just him, you know, especially like, I've never met someone like him. "His character is something unpredictable."
