Can those planning to storm Area 51 expect to see another Zlatan Ibrahimovic? No.

Almost two million people have RSVP'd to a Facebook event to "Storm Area 51" – a classified US Air Force training base in Nevada which conspiracy theorists believe harbours information about extraterrestrial life.

A disclaimer in the Facebook event claims it is all a joke, but it has not stopped #StormArea51 from taking the internet by storm.

When LA Galaxy superstar Ibrahimovic fronted the media on Wednesday, he was asked what might be in Area 51.

"Not another Zlatan. That's for sure," Ibrahimovic joked with reporters.

Asked if they would let Ibrahimovic into Area 51, former Manchester United, Paris Saint-Germain and Barcelona striker Ibrahimovic replied: "I have my own area 51."

Ibrahimovic has enjoyed another fine season in MLS, with 13 goals for the Galaxy.

The 37-year-old's goals have helped the Galaxy to third position in the Western Conference, 12 points adrift of leaders Los Angeles FC after 20 games.
