The Frenchman risks losing a host of players next summer, chief among them Mesut Ozil and Alexis Sanchez, when their contracts expire at the end of the season.
Having resisted multiple offers from Manchester City for Sanchez, Wenger is facing the prospect of doing it all over again in just a few months when the transfer window reopens.
Wenger believes players will already begin thinking about their next move by October – or are even tapped up already – and has called on changes to be made to the current system.
‘What’s happening is the players know the transfer window is closed. September will be OK,’ he told beINSPORTS.
‘The players who do not play or the players who are tapped up in October they already start again to think, “Where do I go in January?”
‘That’s not the way to be on board with the football club. And I believe we have to realise that.

‘We are here to entertain people, and you can do that with people who are really on board, together, to achieve something together, and not every minute that it doesn’t go well to think, “Where can I go next?’”
‘I believe that we have to bring some decency, and we all complain today that it has become too much business. But we can do something about it. We have that responsibility as well in the game.’
A host of Premier League clubs are ready to back calls to have the summer transfer window end before the season starts, and while Wenger supports that motion, he wants to go one step further.
He continued: ‘You cannot have a player preparing for a football game that is today vital because nobody accepts anymore to lose a football game and still be at 4 o’clock on the phone, “Do I go or not? How much is it? When do I have to go?” It’s impossible.

‘These boys are all under high pressure, well paid, you want them at least to have a normal preparation for a football game.’
He added: ‘The ideal situation would be to have a transfer period that is closed 48 hours before the first game of the championship, and to close it completely until the season after.’
