Arsène Wenger has criticised the rules of English football's transfer window.

The manager's dislike of the system is well documented and this summer's dealings have done nothing to change his opinion.

Speaking at Friday's pre-match press conference, the manager suggested that the window should not overlap with the start of the season.

He explained: "I believe that the buys should be over once the championship is started.

"Somewhere when you are manager, you have to make decisions and decide whether you will be successful with a squad or not.

"Once the championship has started, for me, it is 'OK, the race has started, now you cannot change any more'.

"And no window in January either. Because it's too easy to rectify any mistakes that you have made, especially for clubs who have big money.

"It gives better chances to the smaller clubs."
