On Tuesday night, media reported that Maradona, who was watching the game from the VIP sector of the St. Petersburg Stadium, collapsed after the final whistle and was taken away from the stadium.

However, the 57-year-old denied the hospitalisation reports via his Instagram account on Wednesday.

An a member of the ambulance service that helped him has backed him up.

"Our doctors approached Maradona to measure his pulse. He said that he didn't need any medical assistance. The information about his hospitalisation is false," the ambulance worker said.

During the game, the 1986 World Cup winner leaned over a railing and flipped the bird at Australia's opponents, which was caught on camera.

Argentina beat Nigeria 2-1 in their final Group D match to scrape into the knockout stage, where they will face Group C winners France in Kazan on Saturday.
