Hull City's manager has called for social media users to be made more accountable after racist comments about him were made online.
Liam Rosenior said the "unacceptable" posts were seen by his children in response to news he had been nominated for an award.
He said some system of identifying people should be introduced.
The Tigers' boss said it had affected his family, saying "it hurts when my kids are bringing it up".
Rosenior told BBC Radio Humberside Sport he thought the comments "crosses the line".
"I'm not talking about people talk about whether I'm a good manager or not a good manager, or if my team's good or whether we're not good," he said.
