If the Non-League club didn't stick this into the transfer then it's their own fault (despite the alleged Prem team not being very sporting to a grass roots club).
This reminds me, Maidstone United must have been gutted that they didn't stick a sell-on clause onto the transfer to Chris Smalling to Fulham.
It was in the deal as playing in pre season......Fulham say they cant find the time.
Bugging me who the player is and non league team but he went out on loan last year to Gillingham or Southend.
