Cape Town - Kaizer Chiefs skipper Siphiwe Tshabalala has urged his team-mates to learn from their mistakes in recent seasons in order to bag some silverware this term.Chiefs had a difficult first season under coach Steve Komphela after relinquishing the Premiership title to Mamelodi Sundowns and losing two cup finals.The Glamour Boys were defeated 1-0 in the MTN8 final by Ajax Cape Town and 3-1 in the Telkom Knockout final by Mamelodi Sundowns.Amakhosi will open their Premiership season against Wits on Tuesday before facing Cape Town City FC in the MTN8 first round on 26 August."We must try to minimise our mistakes. I think going forward we should just play our hearts out. We must make sure we win each and every game," Tshabalala told The Sowetan."Everyone is looking forward to the new season. It is going to be difficult in a sense that no one is guaranteed a start because of the hard work the players have been putting in pre-season."We need to be more clinical because we do create goal-scoring chances. It is a worrying factor that we are not converting enough."
