I think Banyana Banyana being the only thing right about South Africa for the last decade is a clear sign that it's time we let women handle everything around here. pic.twitter.com/ee2OxKm4zE— Jesse Swiswi (@JayFromVenda) September 22, 2018

Victory once again for @Banyana_Banyana as they win #Cosafawomenschampionship for the 2nd time in a row! Tough final with an equally competitive opponent but the team pulled through with two goals by vice-captain @fifinhojane. Well done to @descaptain and the team! pic.twitter.com/fb7a1amU5K— Official SasolLeague (@SasolLeague) September 22, 2018
