Alessandro Ferreira Leonardo (Chinese: 辛祖; born 10 March 1987), commonly known as Sandro, is a former Brazilian-born Hong Kong professional footballer who played as a forward.

Sandro was sent off after a second bookable offence in the match against South China, when he pressured Zhang Chunhui to take his goal kick quickly and was considered by the referee to have obstructed the goalkeeper.

[2] On 25 October 2009, Sandro scored 5 goals for Citizen against Happy Valley at Siu Sai Wan Sports Ground, including a 50-yard lob.

[3] With Citizen, Sandro won the Hong Kong Senior Shield after defeating South China in the final on penalties.

While Sandro claimed, through his lawyer's advice that the agreement was not legally binding, Eastern's Executive Director Peter Leung took league action after the Hong Kong Football Association was unable to resolve the situation.

On 7 November 2015, Sandro made his international debut and scored his first goal for Hong Kong in a friendly match against Myanmar.
