Cape Town - Kaizer Chiefs striker Kingston Nkhatha admits that his goal-scoring ratio should be better amidst criticism that he wastes far too many chances in front of goal.The Zimbabwean frontman has netted just once in seven Premiership appearances, six of them starts, this season, whilst he also scored just a solitary goal in Amakhosi's five cup games - four in the MTN8 and one Telkom Knockout outing.Last season Nkhatha managed seven goals in his 24 league games and his poor finishing has drawn plenty of booing from the clubs' fans.Over the weekend, he squandered a golden chance to score in the 1-0 cup win against Maritzburg United, pushing the ball wide from eight yards out having done all the hard work to power his way into the box.Chiefs head coach Stuart Baxter has continued to strongly defended him, though, instead praising his high work-rate and never-say-die attitude.But the 28-year-old does agree with most of his critics."I think so (that I should be scoring more goals)," he told Football411. "Every striker needs to score goals."I'm still working on it and I need to score more goals. But on the day if I don’t score and my team-mates score then that's a plus for is."
