West Ham boss Slaven Bilic has warned against Premier League clubs setting their own transfer deadline.

Bilic wrote for the London Evening Standard: "I know the clubs are generally in favour of the transfer window closing before the start of next season - but I do foresee some problems.

"The window will still be open in other countries and that could lead to players leaving and you not being able to sign replacements, which would make matters even worse.

"Take Liverpool, for example. If that rule changes, it would technically still not stop Philippe Coutinho going to Barcelona but it would prevent Liverpool signing a replacement.

"Yes, it would be better if the window was closed before the start of the season but only if it is right across the rest of the leagues in Europe. Otherwise, it could be even worse than it is now."
