Uefa president Michel Platini is keen to meet with Fifa to open a debate regarding the future of the transfer window.
The recent January window has come in for criticism from several Premier League managers, who want a change to the current system.
Platini believes there are tweaks which could be made to improve the situation and expressed concerns about David Beckham's short-term move to AC Milan.
The former France and Juventus star believes discussions are needed in an attempt to produce a transfer system which meets with widespread approval.
"It's not a problem of what we have to do or how long, it's a problem of tactics," Platini told Sky Sports News.
"It's a case of if we can change it, when we can change it and where we can change it - that is three questions we have to think about.
"I think at the next meeting with Fifa we will speak about it for the future because we have to have a regulation all over the world.
"With Beckham in Milan, he has a contract for three months, and if you have a contract for three months that means in the final of the Champions League we have Chelsea or Manchester who can buy a player for two matches!
"We have some questions on the regulations to respect. I have no idea, but we can open the debate."
