Blatter served as FIFA president from 1998 till 2015 but stepped down in June 2015 amid a massive corruption scandal and was subsequently banned by the FIFA Ethics Committee for eight years, later reduced to six.
"I'm here to enjoy the World Cup", he told reporters, smiling.
The ban on Blatter from "all football activities" was imposed shortly after the Swiss attorney general's office began criminal proceedings against him on suspicion of criminal mismanagement and misappropriation.
No charges have yet been brought and Blatter has repeatedly denied any wrongdoing.
"I think that England deserved to organise the World Cup".

Speaking to Sky Sports News, the former FIFA President said that England and the United Kingdom were overdue the World Cup having last held it in 1966.

"This is what I introduced in 2011", said Blatter.
"I feel a little abandoned because I am suspended, but I am still the elected president".
When asked how he had been occupying his time since the ban, Blatter said he was grappling with how to solve the problem of political intervention in world football.
