If Liverpool want to protect their investment, they'll terminate this loan early Jan.
Emery doesn't want him so best for all parties to agree it was a 4 month fuck up and call it a day.
There was a discussion on Sky Sporys News about him earlier today. The reporter was outside Villa Park and said that it's likely Emery doesn't rate him and certainly doesn't want to fork out £35m for him, so it's unlikely that we will see him play for Villa again.
Unless he's done something badly wrong, it's hard not to feel a bit of sympathy for him.
