Move to Leicester (or potentially anywhere in UK) could be off due to tax implications.
Apparently to do with how much Zaha is taxed in Turkey compared to UK (20% Turkey; 45% UK), and that he would have to pay some money back to HMRC if he moved back here as he hasn't been out of the UK/in Turkey long enough to avoid doing so.
I doubt this would happen for us now, which is a shame. Apparently we'd have to pay him something like £150k/w to cover the costs for Zaha, and there's not a chance we could stretch to that.
