Former FIFA president Sepp Blatter has accused his successor, Gianni Infantino, of disrespecting him since becoming president of the world governing body.
Blatter, who had been in charge of FIFA from 1998 until 2015, is facing a potential life ban from all football related activities after he recently lost his appeal against his suspension at the Court of Arbitration for Sport.
The 80-year-old Blatter and former UEFA president Michel Platini were suspended in December last year over a £1.3 million 'disloyal payment' made to the Frenchman in 2011.
Infantino, who like Blatter hails from Switzerland, was elected as FIFA president in February and Blatter says their relationship has turned sour.
He told the BBC's World Football: "I have never seen in any company the new president not paying respect to the old president.
"After his election we had a very good contact and he stopped at my house and we had a chat and we drank a glass of red wine. I told him I have a list of questions that should be solved in FIFA which has not been solved before.
"He said, 'I will work on that', and he never came back. I have asked him, I have sent him a letter and I have his personal number and I was told that it's still correct because I have some connections. I sent him emails.
"Never, never an answer, never. Now we speak only through lawyers."
