It's how we're trying to do all deals. It's basically our way of financially managing the risk involved in signing a young player. If he doesn't meet his potential or our expectations we've put down a lower sum so offset some of that risk. Rightly, Everton want the full fee now, but as with other deals I'm sure we'll get our way.
Add-ons probably take an age to negotiate because we'll probably say we'll pay £X on X no. of appearances and Everton will haggle and say we'll pay £X amount more on fewer no. of appearances. It becomes a deal within a deal. With the amount of cash we're paying at the moment we're needing to offset as much money as possible when we've so many players still on the books we need to, but are struggling to shift.
It will get done and I think it will be around the £40m mark with potential to rise to £50m.
