Not sure how many here are realistically able to comment, but I would say that Kraev's Kiwi partner would find it hard to follow to an unknown European (or Asian) city with a small baby without her whanau support, and her partner away every second weekend. If a club in New Zealand or in Australia makes him a decent offer after his current contract expires this looks more likely an option she would agree to rather than going to an unknown city halfway across the world.
Yeah that would be a fair call. Though a Bulgarian English speaking nanny would be pretty cheap, and a great help if Kraev left for elsewhere. Can be good fun raising kids in a bilingual household. Apparently it can help their learning development, and with 50% papa's genes, my ninas for example need any edge they can get.
