Greening is being loaned to Fulham I think.
I think this is the player basically bargaining with the club, saying I want to play in the Premiership, loan me this year and I'll come back and play next year if West Brom get promoted. Rather than them losing him completely.
I assume West Brom are getting a fair fee for the loan as well.
Either that or I have totally the wrong end of the stick here.
