Arsenal manager Arsene Wenger has called for the transfer deadline to be moved to before the start of the season.
As it stands, the currently window will end on September 1, but Wenger claims that changes would make the system fairer.
He is quoted by The People as saying: "Does it bother me the window is still open? Yes, because it creates uncertainties. At the start of the season everybody should be committed, not half in, half out.
"The other handicap is that a player could play against you three times for two different clubs.
"He plays against you, then plays against you for another club. We say, 'Oh, you have to love the shirt'. But within the same season he has to love two shirts."
Arsenal open their Premier League campaign at home to West Ham United on Sunday.
