Hazard's time with Real Madrid continues to be plagued by injury.
But Vermaelen told Goal: "First of all, everyone is quick to get injured and that sort of thing. I think he had a blow to the ankle. It is not his fault. It must be a muscle injury, I don't think it's serious."
Vermaelen continued: "For me, personally, he is a world-class player. I played against him in England. He is very positive. When he comes back and starts playing, you will see the best of him.
"He does not worry me. He will come back."
