BBC Sport - BBC Unsung Hero: Visually impaired tennis players express gratitude for volunteers
'I owe them so, so, so, so, so much'
- From the section Get Inspired
"None of this would be possible without the lovely volunteers," says Naqi Hiader Rizvi.
He is just one of the many visually impaired tennis players benefitting from people helping put on their regular sessions in Finsbury Park in London.
Jessica Bavington, who started volunteering in the role about six years ago, is one of those.
"I was just absolutely fascinated by how it was even possible that someone could play tennis with potentially someone who's blind," she said. "It was just profoundly inspiring.
"Some people will see barriers in volunteering and actually there are not that many."
