Diego Maradona hit out at reports that suggested his health was on the wane after he received medical treatment at the World Cup in Russia, appearing on television to say: "I am more alive than ever."

The 57-year-old soccer great sparked concern when he was pictured being treated by paramedics after Argentina's pulsing 2-1 victory over Nigeria in St. Petersburg on Tuesday, but he insisted he was not taken to hospital.

In an interview with Telesur, Maradona suggested that his condition was exaggerated by people who envy him.

"I want to let the whole world know that I'm more alive than ever," he said. "Unfortunately, I can't make mediocre people good.

"There has been talk of stretchers, ambulances on the Internet which triggered a cycle of meaningless lies.

"I understand the envy, but don't tell lies."

Maradona drew the attention of TV cameras by dancing, celebrating and making obscene gestures to the crowd as Argentina confirmed its place in the World Cup knockout phase.

Goals by Lionel Messi and Marcos Rojo ensured that Argentina finished second in Group D, having taken four points from games against Iceland, Croatia and Nigeria.
