QPR director of football Les Ferdinand believes that the removal of the emergency loan window will force clubs to quickly get their houses in order.
Clubs are now unable to make temporary signings from Premier League clubs outside the summer and winter transfer windows; goalkeepers are an exception to the rule if there is an injury crisis.
And Ferdinand believes that, while it will cause issues with players struggling to get minutes, it will encourage teams to be more measured in their business.
He said: “If you’re a professional footballer and know you can’t play for six months you’re not going to be the nicest person around the building.
“It’s going to help everybody to get their house in order quicker than they perhaps have done and this is a test case for it.
“I’m pleased the emergency window is closed, because now we’ve got our business done and now we can concentrate on the players that we’ve got and going forward.”
There is also a hope that it will force clubs to rely on their under-21 players and Hasselbaink believes that will be the case although some clubs have been stockpiling players to prevent such an issue.
The QPR director of football added: “If I get an injury between now and the end of this month I can’t bring anybody in.
“Will that encourage clubs to bring people through the system and play the younger players?
“You never want to stop bringing players through but they have to be good enough to be in the first team.
“Sometimes you see them in the Under-21s and they go into the first team and they’re actually better than you imagined.
“People have stockpiled, in the Premier League especially because they feel they need to have players around.”
