the United States, Canada, Japan, China and South Korea are good examples. Alternatively, some clubs within the European Union have used feeder teams to sign non-EU players and then naturalize them in an EU country, to overcome visa regulations, for example English team Liverpool F.C. has an agreement with Belgian side KRC Genk.

In the 1960s, several NFL teams had agreements with the Atlantic Coast Football League to use their teams as farm teams, though they were not owned by the NFL owners. The most recent official minor league, NFL Europe, was different from most other farm teams in that all prospects were pooled and dispersed among the six European teams, instead of having teams assigned to each other.

A similar system was used by NFL Europe. Many players in the Canadian Football League and Arena Football League (among other indoor American
