Arsenal manager Arsene Wenger believes the current loan system for Premier League clubs is "not defendable".
At Goodison Park on Sunday, the Gunners take on an Everton side which has been boosted by the temporary signings of forward Romelu Lukaku from Chelsea, veteran Manchester City midfielder Gareth Barry and emerging Barcelona talent Gerard Deulofeu.
While Wenger has no issue as to how any club manage their loan deals, the Arsenal boss is adamant there is a strong case for change -- particularly concerning the rule players cannot face their parent clubs.
"Everton have done a quality job on that front, because they got Barry, they got Lukaku, they got Deulofeu that have done very well with them," the Frenchman said.
"I believe if you want to continue the loan system, we have to make them available against the teams that loan them out, or the system is not defendable. It is just a protection of the clubs who loan the players out to hurt their opponents and they have no risk at all.
"I think the best would be that the players are only loaned in lower divisions or abroad, and even abroad I am not completely convinced it is right.
"It is just to get the player to play somewhere at the top level and see how good he is, what we will try to do as well, you know, but it raises a little bit the question.
"It is not against Chelsea, it is not against Man City. The system is for Chelsea like for everybody else, like for Arsenal and everybody else. I think the whole system has to be considered again.
"As a whole, the only question you ask is, 'is the system right or not?' It is open to debate. I'm ready to accept any decision."
