Sure we had a decent sell on and we only sold for 500k. If he's going on a permanent but wouldn't be suprised if Everton were giving him away.
I thought at the time was 500k rising to 2million with add ons he didn't have long left on his contract and wanted out... could be wrong though. Doubt we will get any sell on if Everton paid 2million can't see west brom paying more than that for him.
I don't know how sell-ons work with add-ons, @redrum, but either way I agree - we're unlikely to get anything more from that transfer.
