Thpurs fed United (Berb, Carrick etc) for years obviously, but now, in a bid to match their North London rivals, they have announced they have become RM's official feeder club. Arsenal have been Real rivals Barca's main feeder for years, and in an uncanny parallel, they have also fed United's main rivals, City. So you decide; who is the better feeder club... Arsenal to City Barca Thpurs to United Real
Obviously Spurs... they signed a document to declare themselves an official feeder club. Arsenal are just unlucky getting players poached. They are not a feeder club.
levy accepts Spurs are going to be a feeder club for the foreseable future, and Levy will make sure they get the best deal out of it, that's for sure.
