Simple but it works really well looks wise. I can't imagine players wear a shirt with such an odd buttoning system though.

Could do with a number and maybe something a little else on the socks.

Btw what is that on the right side of the shorts? (Not the Japanese flag)

On the shorts is the Massimo logo. And I don't really know how the buttons would work, but the design is supposed to be Japan orientated so I thought they would suit.
