Former FIFA President Sepp Blatter has left intensive care after major heart surgery.

The 84-year-old Swiss was kept in an artificial coma for a week.

"He is making progress every day, albeit in small steps," his daughter Corinne Blatter Andenmatten told Swiss media on Friday.

"The doctors are happy with his condition, but there is still a long way to go."

Blatter tested positive for the coronavirus in November and underwent heart surgery at the end of the year.

According to his daughter, the operation was "more complicated and more dangerous than previously thought".

It is not the first time that Blatter has struggled with health problems.

In 2015 he had to be treated in intensive care because of an immune system disorder.

A year later, the Swiss was operated on for skin cancer.

Blatter led FIFA from 1998 to 2015. He is currently out of a six-year suspension due to a dubious € 1.8 million payment to then UEFA president Michel Platini in 2011 and has been banned from all football-related activities.

In December, FIFA filed another complaint against him for a suspicion of criminal mismanagement at the very expensive FIFA museum, which opened in 2016.

The costs amounted to about 500 million Swiss francs (approximately 461 million euros).
