Major League Soccer commissioner Don Garber has set a Friday deadline for AC Milan to agree a deal to sign David Beckham from the Los Angeles Galaxy.
Any deal would have to be approved by Garber, but he told reporters on a conference call on Wednesday that he wants a deal in place by the end of the week if it is to go ahead.
"There is no reason why this should drag on," Garber said. "They (AC Milan) either want to do it or don't want to do it. This Friday we need to know if they want to buy David Beckham or not."
Beckham joined Milan on loan at the beginning of January, saying he wanted to keep up his match fitness to remain in the England squad.
The deal is due to expire on March 8, but Beckham and Milan have made clear that they now want to make the switch permanent.
Garber, however, insisted MLS would not be made to wait as the start of the American season nears.
"What they need to realise is that we are getting very close to the start of our season," he said. "We have to figure out what plans we need to make and if David Beckham is going to be a part of those plans."
The Galaxy's season begins against DC United on March 22.
Beckham, who signed a five-year contract with the Galaxy in January 2007, has impressed during his month in Italy, scoring twice and earning a place in the Rossoneri's UEFA Cup squad.
He announced last week after a friendly in Glasgow that he wanted to make the move permament.
