Zlatan Ibrahimovic's off-the-field investments and "incredible" intelligence will make him a billionaire, according to his agent Mino Raiola.
The Sweden international has enjoyed a glittering career to date, winning league titles in the Netherlands, Italy, Spain and France, while he also won the Europa League and the EFL Cup at Manchester United.
Ibrahimovic, 36, has now moved to the U.S. with LA Galaxy after his contract was cancelled by mutual consent by United.
Raiola boasts an array of stars in his client list, including Mario Balotelli, Paul Pogba and Romelu Lukaku.
But the Italian super-agent, who earned a staggering €27 million from Pogba's £89m (€105m) transfer to Old Trafford from Juventus, insists that Ibrahimovic has the business nous to outstrip their wealth.
"Zlatan’s the cleverest of them all – and the richest," Raiola, who speaks with Ibrahimovic four times a day, told Dutch magazine Quote .
"He has it within himself to be worth £1bn. He’s incredibly intelligent and active in the market. I only have to tell him something once.
"Ibra is invested in gaming, tech start-ups and diamonds. He’s already sold big shares to hedge funds which no-one knows about. He’s earning far more away from football then he does in it.
"When I do a deal for him, he jokes: ‘You’re going to steal a lot of money from me again, aren’t you?’
"My answer to him is always the same. ‘First, I make you rich – I can’t steal from the poor, can I?’"
Forbes estimates that Ibrahimovic is currently worth £22.6m.
Raiola insists he always strives to ensure his clients end their careers rich, and says he always advises players to invest in property.
"But it’s the same when all my players are finished. They will have a lot more money than when they started," he added.
"I try to protect them from financial blunders. For instance, I have an agreement with the banks that they let me know when the players spend big.
"I’ve told them that Amsterdam is the cheapest capital in the world. I’ve told them: ‘Buy every property there that you can lay your hands on.’ Winners have a plan, losers have an excuse.
"It’s a good job for those big property tycoons that I went into football – otherwise I’d have owned half of Amsterdam."
