Former Napoli and Barcelona star Diego Maradona has denied reports he's suffering from Alzheimer's.

The Argentine icon, 58, insisted he is "not dying" from the irreversible brain disorder in a video posted to his Instagram page.

Cronica published a report that claimed the retired footballer was suffering with "neurological problems" and the "start of Alzheimer's".

In a clip posted to his 4.8million followers, Maradona raged: “They're lying, they're lying. They speak of Alzheimer's and they don't know what it means.

“The word Alzheimer's is an awful word. People with Alzheimer's die. I'm not dying. These sons of they know what throw it out there to create confusion. I don't do confusion."

His lawyer, Matias Morla, has insisted Maradona stepped down as manager of Mexican side Dorados last week to focus on his health and undergo shoulder and knee surgery.
