Kaizer Chiefs coach Steve Komphela admitted new boy Siyanda Xulu is worried about the holes in his team's defence. Following their 1-1 stalemate in the first leg of the MTN8 on Sunday, Komphela said Xulu complained about having different partners at centre back since his arrival at the club, a set-up he felt destabilised the back four.Chiefs conceded just 15 goals last season , but have already been breached four times in their three official matches under Komphela, one of these being a 5-3 win over Maritzburg United in an MTN8 quarterfinal clash .Said their coach: "Xulu had been changing partners and at some stage he came to me and [assistant coach] Doc [Khumalo] and said: 'Gentlemen, I have been changing partners like I don't know what, playing with this one and that one. Maybe when there's consistency it gets better.'"Sometimes you don't have a choice but to stick with what you have and for now, Xulu and Eric Mathoho are doing the job for us."In our team talk we also made mention of the importance of the central pairing."I remember during pre-season we had Xulu and Lorenzo Gordinho because Morgan Gould, Mathoho and Daniel Cardoso were all out."These guys are not machines. Any player who comes back from a lengthy lay-off [lacks] match fitness."Komphela, himself a former defender, suggested it was only a matter of time before the Amakhosi rearguard will solidify.The defence is also without Tefu Mashamaite this season after he moved to BK Hacken in Sweden.Gould and Cardoso are still on the injured list.The coach said: "It is only fair to admit that any team that wants to win any knockout competition has to lessen the number of goals they concede."And the fact that when Chiefs went on to win it, they won it without having conceded - that's a great inspiration. I don't want to say we are shaky - maybe we are not as cohesive."Komphela felt his forwards were faring well. He has been trying to give striker David Zulu and Siphelele Mthembu an equalopportunity to prove they can play alongside Bernard Parker."I think Siphelele played very well and the confidence from Zulu was a notch higher. So you try to get all the strikers confident enough and, when that happens, it will trigger the right technical application to score. We still have [Bongani] Ndulula. We will work on in it, that's what we get paid for."..
