The summer transfer window is under way and already we've seen a major transfer as Eden Hazard departed Chelsea for Real Madrid in a £100million deal.
That deal won't be the last big move ahead of the deadline in August as clubs prepare their sides for the new season.
In the EFL clubs can rely on loan players to bolster their squads but it's not the same in the Premier League.
Top-flight regulations mean that clubs can only have a maximum of two players on loan from other Premier League teams, and only one from any given Premier League club.
Newcastle have used the loan market with varying degrees of success under Rafa Benitez, with Salomon Rondon a big hit last term.
Goalkeeper Martin Dubravka's loan move in January 2018 was a key success, with the Slovakian making the deal permanent last summer, while Brazilian Kenedy shone in his original loan spell, but couldn't replicate that form last season.
The rules, which can be found in the Premier League handbook, state:
- 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.
Cardiff City manager Neil Warnock hit out at the current loan system describing it as scandalous in December.
He said: "Heaven knows why we can only have two Premier League loans in."
"When you are talking about English players needing experience - our younger players for the English team - and we can't loan more than one more player.
"I've got Harry Arter, so I can't take a young English striker or a young English midfield player, if I've got another one (on loan).
"It's scandalous, really. You can bring 10 from abroad, so who are we trying to help?
"Who has invented these rules? It's a disgrace, really, when I could be giving another good young English lad an opportunity of playing in the Premier League."
