The Gunners face Everton on Sunday and in-form striker Romelu Lukaku is stealing the headlines yet again for the Toffees with impressive, consistent performances.
Wenger’s issue with the system is that a player on loan from a club – in this case Chelsea – cannot play against their parent club when they meet in the league.
The Gunners boss feels this gives not just Everton an advantage for having a fine young talent, but also Chelsea as their player can play against and damage all of their title rivals but not themselves.
“Once you are on loan, it should be a transfer – you play for the club,” Wenger said.
“You cannot play for the club only in 19 games and not against another club.
“If Lukaku didn’t play for Everton, somebody else would play. I don’t make a fuss of that, and it is our performance that will dictate the result on Sunday – not only Lukaku. He is a good player, but the rules are the rules and we have to accept the rules.
“If you ask me my opinion, I am not against loans, but you should be capable to play against everybody.”
