Loans between Premier League clubs and other English counterparts are officially called temporary transfers.
Under the rules in the
Premier League Handbook 2021/22 (Download PDF, size: 21.6MB), there are restrictions on how many players Premier League clubs can loan from other Premier League/English clubs.
They are:
- Premier League clubs may not register more than two players on loan at any one time.
- The maximum number of loans registrable in the same season is four, and, under no circumstances, shall more than one be from the same club at any one time.
- Premier League clubs cannot loan to another Premier League club a player they have acquired in the same transfer window.
- A Premier League club may loan not more than one of its goalkeepers to another Premier League club.
That doesnt mention International loans, so I might be wrong.
