Apparently Jose Mourinho did not want Sheva as much as Roman Abramovich did. As for Sheva he really did not mind going either to Manchester United or to Chelsea. It was left to Kristen Pazik, Sheva's wife, and a well known American model, to decide that Chelsea , or more to the point, West London was a better deal.
But it was not easy, Abramovich's wife, Irina had to befriend her, host her at their Belgravia mansion and squire her around town. As a result of her five-star guided tour Kristen was, apparently, ready to "confirm her approval of the lifestyle change". Fuddy duddy Manchester was dropped for swinging West London.
I have no idea what Pazik models but here are some pictures and they are ummmm..... a bit risque
