Wilf
Might leave next summer, but it at least confirms a decent payment for his services, dunno who he'd end up going to if he does leave mind, he's likely out of the Spurs price range, wouldn't be a confirmed starter at Liverpool or Citeh, doubt he'd return to Man Utd for another go...
Pretty much leaves Arsenal or Chelsea (as a Hazard replacement) or a foreign team...
I'll enjoy his presence at Palace for as long as I can
