After a bit of googling - Liverpool have the same number of players out on loan as we do - seventeen. Obviously some of ours are not U21s - Alzate, Undav, Rushworth, and Dahoud at least - and I think Scherpen and Leonard too (and there maybe more); don't know what the ages of Liverpool's...
If Leonard is as good as Northampton fans think he is, then definitely! I'd add Weir and Sarmiento to those two as well - and maybe we'll finally find our new no.1 GK is already on the books!
