Arsenal manager Arsene Wenger has suggested a ban on loans of players over the age of 21 as a solution to the current debate regarding the market.
The present economic climate has seen many clubs turn to temporary player exchanges, which see both parties benefit from avoiding a permanent transfer fee and the possibility of shared salaries.
But some critics have issue with the rule which prevents loaned players from featuring against their parent club when they are allowed to face, and potentially do damage against, all of their other rivals.
A prime example is former Arsenal striker Emmanuel Adebayor's move from Manchester City to Tottenham, who he has fired above the Gunners in the Premier League after nine goals in 19 games.
But last weekend the Togolese forward was not allowed to face City, when Roberto Mancini's men defeated Spurs 3-2, and that has led to renewed suggestions that the parent club is the significant benefactor.
Wenger, who has 31-year-old Yossi Benayoun on loan at Arsenal from Chelsea and Thierry Henry back with the club on a short-term basis from New York Red Bulls, said in the Daily Mirror: "Personally, I would not ban players on loan from playing against their own clubs.
"What I would like to see in the Premier League is that you are not allowed to loan players over the age of 21."
He added: "At the moment it is an opportunity for some clubs to reinforce other teams, without losing ownership of the player.
"For example, if a big club sends a big player to another club in the Premier League on loan, they only have benefits.
"That player cannot face his own club, yet he could win games against their rivals.
"Therefore, I think it would be better if players over 21 didn't go on loan in the top league."
In an attempt to avoid contradicting himself, Wenger has also defended his decision to sign Benayoun.
He said: "It's true that I haven't done that often. But we were on the last day of the transfer window. We knew that Jack Wilshere would need surgery.
"So we were short in midfield at that point and to find two players so late was nearly impossible for us without using a loan.
"At that time, the most important thing was just to sign him."
