Salah said he was particularly annoyed with a team banquet hosted by Chechen leader Ramzan Kadyrov, who used the dinner to grant Salah "honorary citizenship," according to the two people, both of whom spoke on the condition of anonymity because of the sensitivity of the subject.
Kadyrov has been accused of human rights violations.
Egypt soccer federation spokesman Osama Ismail said that Salah has not complained to the federation. "Only what Salah writes on his Twitter account should be counted on."
