Xavier, 35, counts David Beckham as a close pal - but says former Chelsea manager Gullit forced him out of the California club. Xavier fumed: "He used language that was not normal and he was very arrogant.
"He was a great player but he is not a great coach. I demand respect.
"Gullit had similar problems when he was at Chelsea and all the players at Galaxy have the same opinion."
Dutchman Gullit had claimed Xavier was a "bad apple".
