Juventus with black shorts and socks just doesn't look right at all. Having a white away kit AND a white goalkeeper kit makes it even more pointless. I won't even comment on the zig-zag lines! What kit will Juventus wear when they travel to Cesena and Udinese? I know in previous seasons they have retained the previous away kit as a third choice, but seeing as last season's shirt was silver grey, that to me would clash badly with any white-shirted team.
I don't get Nike, their international shirts are alright, if nothing special, but most of the club shirts I have seen have been awful with this emphasis on the zig-zag patterns.
By the way that Sporting CP away shirt is really good I think.
