Nainggolan's half-brother: 'I am worried about him. He does not listen to me'
"What is happening? I do not know. I try to call him, but he does not answer. I am afraid there are some family problems at home. He does not listen to me. People say I have to be harsher with him, but it's as if my words have lost all effect on him. A psychologist? It would help maybe for a week. Then Radja would fall back into his habits as he has done all his life," he said.
"I think he is doing less than half of what he could do with the talent he has. The national team? My opinion on this has not changed. Roberto Martinez would have to take him all the time because if you are a great coach, you have to be able to handle a character like Radja," Manuel added.
