piqué/puyol is the #1 partnership and rightly so.
after that we've got options. piqué/milito was the business at zara 3/4 years ago, so I reckon that could work nicely. chysus/milito showed last night that it has legs as a partnership - and by that logic chysus/puyol would be quite good if not better.
chysus/piqué doesn't work in theory but neither did rafa/piqué in theory. in practice it was the tits. but chysus has to be fully settled and acclimatised for it to work, so I dunno if we'll see it much this season. in the future, probably.
but for now those top four are the ones to look at.
