Former LA Galaxy general manager Alexi Lalas said he would not be surprised if David Beckham did not to return to America after his loan with AC Milan.
The England midfielder's stint with the Italian club ends in March, when the Major League Soccer season resumes.
Lalas, who in 2007 signed Beckham on a five-year contract with the Galaxy, told BBC Radio 5 Live: "If I was still at the Galaxy, yes, I'd fear it."
But Beckham's spokesman Simon Oliveira insisted he would return to the Galaxy.
He said: "Whilst we respect Alexi's right to an opinion, he has not been party to any contractual discussions on the loan agreement to Milan.
"As David has said recently, he will be back in the US for 9 March and with LA Galaxy for the start of the MLS season."
Beckham played for 45 minutes on his Milan debut as the Serie A giants beat Hamburg 4-3 on penalties in Dubai on Tuesday.
The 33-year-old joined Milan in a bid to prove his fitness and regain his England place after being told by England manager Fabio Capello that inactivity during the MLS off-season would result in his likely omission from the next squad.
Lalas feared that the former Manchester United and Real Madrid player would not want to return to the MLS after playing in a star-studded line-up featuring the likes of Ronaldinho, Kaka and Andriy Shevchenko.
However, the former USA defender added that Beckham's "desire to prove people wrong" after an uninspiring first two seasons in the MLS hampered by injury, may entice the midfielder back across the Atlantic.
"I think he wants to do well with the Galaxy but you only have one career," said Lalas.
"The experience he's going to have at Milan will benefit him individually, how much it benefits the Galaxy and the people that are ultimately paying the majority of his wages remains to be seen.
"He's back in his comfort zone at AC Milan, playing with one of the biggest clubs in the world, with a tremendous amount of talent around him, with incredible money out there on the field so it must be, in a weird way for him, a relief to get out there."
Lalas, who played for Padova in Serie A, insisted LA Galaxy and the MLS would survive the post-Beckham era.
"Any manager, to a certain extent, wants David Beckham on their team but I also think David Beckham is not bigger than the Galaxy, nor is he bigger than Major League Soccer," said Lalas.
