Arsenal manager Arsene Wenger hopes to see a change made to the stipulations of loan deals that would allow players to compete against their parent clubs, as the Premier League leaders prepare to face current star of the system, Romelu Lukaku.
Premier League rules prevent loanees from playing against their full-time employers which means that Lukaku, who has scored eight goals this season, will be unavailable when Everton face Chelsea.
The Belgium international can, however, be selected for all other fixtures during the campaign, with Lukaku's next outing against Arsenal at the Emirates Stadium on Sunday afternoon.
A reversal of this rule would provide more of a level playing field, says Wenger, who believes a loan deal should be treated in the same manner as a permanent transfer.
"The system of loaning out players has existed for a while. I'm not against it, I just think that the players should be allowed as well to play against the team who has loaned the player out," he told reporters on Friday.
"I always did plead for that because there is no reason once you signed for a club that you should not be allowed to play against everybody.
"When you sign for a club it means 'I commit for every single game I play for this club' and there should be no exception."
The rule in a previous life allowed players to meet their parent side if permission had been provided, and Wenger has previously allowed Arsenal youngsters to face his team during their spells away from the club.
He added: "Of course at some stage when I arrived in England you could decide if you loan a player out can he play against you or not, I remember I had that case with [Francis] Jeffers when I loaned him out and I always said 'yes if I loan a player out I allow him to play against us' - even if in the case of Jeffers he scored against us. I just think it is right."
