Alan Oliveira looking to emulate London 2012 success in Rio

Alan Oliveira, who won a surprise gold medal at the London 2012 Paralympics, says he wants more glory at Rio 2016.

Oliveira says the "Paralympics were as grand as the Olympics and left a legacy, and now the two Games share the same importance."

The Brazilian is now turning his attention to defending his title in his home country, as BBC Sport's Dan Roan reports.
