The 50-year-old star is said to favour London over a US venue because he still enjoys huge popularity across Europe, the Daily Mail reported.

The singer who according to some reports is suffering from many health problems including a lung infection and a skin disease plans to silence his detractors with the performances which might fetch him more than USD 2 million per night.

"It will be the greatest comeback in the history of pop and there would be no problem selling out the O2 every night. No-one is concerned about his reputation and people don't feel it is a risk.”

"Organisers are confident people will come from all over the world to see him. There have been rumours about his health but that is not an issue. He is capable of doing all the shows," the organisers AEG Live told the newspaper.
