Sepp Blatter has accused new FIFA president Gianni Infantino of disrespecting him.
Blatter was succeeded by former UEFA general secretary Infantino as FIFA chief in February, following a tenure spanning more than 17 years.
Blatter and his UEFA counterpart Michel Platini were suspended from all football-related activity by FIFA in December 2015 when the adjudicatory chamber of its Ethics Committee ruled a payment of two million Swiss francs, authorised by the Swiss to the former France captain, constituted multiple infringements of the FIFA Code of Ethics.
That eight-year ban was initially reduced to six years and earlier this week, the Court of Arbitration for Sport dismissed Blatter s appeal and ruled that his suspension would remain in place.
And the 80-year-old is not impressed with the behaviour of his successor Infantino.
I am definitely not a happy man [with] what happened with FIFA, Blatter told the BBC.
I have never seen in any company that the new president was not playing 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. I told him I have a list of questions that should be solved in FIFA which has not been solved before.
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. Never never an answer never.
I still have this list, so now we speak only with lawyers.
