Aliko Dangote, Africa’s richest man, plans to buy London-based Arsenal soccer team within four years. Dangote, a Nigerian worth $10.8 billion, according to the Bloomberg Billionaires Index, announced his intention to buy the club last year. He said he needs to wait for his business prospects to improve and his investments in gas pipelines and an oil refinery to play out before making the acquisition. “There’s no doubt” he’ll buy Arsenal and “it’s not a problem” of money, Dangote said in an interview with Bloomberg Television in New York on Wednesday. “Maybe three to four years. The issue is that we have more challenging headwinds. I need to get those out the way first and start having tailwinds.
