Just a thought amongst all the uncontrolled paper talk that is continually circulating. The three outcomes that I belive are most likely;
1) Louis stays put. His only loan move that has worked is the one to County. A loan move elsewhere does not mean game time and could also see a demise in form. He only just signed a new contract with Villa, why would they sell?
2) County buy him with a buy back clause. This is a new way to do buisness in transfers. effectively a pseudo loan. Mark Stott is a buisnessman and paying 4 Million for an asset that will be worth 8 Million in 2 years is simple buisness.
3) He goes back to Villa to augment the squad. Although less likely. If you were a Villa owner would you sell him to Leicester? I doubt it. But if Louis is rated, why sell him to a.bigger club where a buy back clause would be unlikely to feature

Just my thoughts. I think/hope he will stay put but January will be a distabilising month for him will media talk.
