Beckham is set to join AC Milan on a loan until the end of the season but could then make his move permanent.
The Los Angeles Galaxy coach said: “On the surface, it sounds like an odd proposition.
“I don’t see where that benefits MLS or the Galaxy. I don’t know if there’s anything true in the rumour.
“I would think given the position the Galaxy is in and the fact that we’re rebuilding our team and trying to have a successful year, it would seem very odd to me if we were loaning out our top players at the start of the season.
“It would seem pretty odd to me to operate that way.”
