Milan will kick off a US tour with a friendly against the Galaxy at the Home Depot Center on July 19, a match arranged as part of the David Beckham "timeshare" agreement between the two clubs.
"He is a Galaxy player who is on loan at AC Milan so he will be playing for the Galaxy," Gandini said.
"I honestly don't expect (fan hostility) because the decision that has been taken by David has been taken with the co-operation of the Galaxy and the MLS.
"I would like to thank both the Galaxy and the MLS for awarding permission for David to stay with Milan until the end of the season. It was a decision that was very important for us in understanding David wanted to play in Europe for longer than expected."
He said the tour would underline how important Beckham had been to Milan both on and off the pitch.
"This should be a great opportunity I think for soccer fans to see the reasons why Milan desired David Beckham to stay longer to the end of the season and unfortunately for the MLS for part of their season.
