"Handanovic is unreal," the former goalkeeper told Sempreinter.
"He's carrying the team with his great saves. It almost seems like the norm, but I think it's certainly not normal.
"He should be given more acclaim, this goalkeeper, he really excels and doesn't get downhearted. He makes great saves. It's difficult for him, because the defence suffers at times, but he's always ready."
