The Premier League has never had a max number of foreigners allowed. Back in the Wenger managerial days Arsenal named a matchday squad of all foreigners.Snoop according to Wiki I think it was wider than that.
Interesting that Wiki note that "It is also intended to reduce the increasing gap between the big and small football clubs. " - now what would us Grecians like ?
