actually it's simple he was rewarded for good service ... The fee was to be paid at the end
Rember he wanted to develop a career overseas and all that was asked was fee at the end or return to play for us
and this was in his contract? Or it was the anticipation of selling him to the J league club with Arnie coaching there as a transfer fee to a foreign club as a kind of gentleman's agreement that hasn't panned out?
and was there simply no possibility in the contract of him being released early from his loan? In which case if the contract was with the club it seems staggering they were not aware of the situation or considered that possibility.
