'I felt pressure, so I lost a point at the beginning.
'It was a very close match, but finally my tactics came into play.
'All my bouts today went right to the end - I wrestled with the Paralympic champion from Cuba (Isao Cruz Alonso) and the German player (Matthias Krieger) who are all strong, so all the bouts were tough.'
In the women's divisions, Azerbaijan's Afag Sultanova beat Lucia da Silva Teixeira of Brazil to -57kg gold with an ippon.
