Cape Town - Mamelodi Sundowns legend Zane Moosa is not impressed with the club's new acquisition, Colombian striker Leonardo Castro.
Moosa believes Cardoso is not better than some of the strikers already on the books of Sundowns, including Bongi Ntuli.
The outspoken television pundit said the signing of Castro was redundant, as the club already has strikers that boast similar qualities.
Moosa also highlighted the wasteful expenditure on Ivorian defender Smourha Bangaly and Burundian forward Fiston Abdul Razzak.
"Castro, I'm not so sure about him. He has not really impressed. He looks very slow," Moosa told Goal website.
"Ntuli was on-loan at AmaZulu towards the end of last season and scored goals for them. He is now on-loan at Platinum Stars and he is doing the same, scoring goals for them.
"So it's a tough one, but I think you should first look at what you have and how they can help the situation before bringing in someone we don't know of from another country."
