Who is Juan Sartori, the multi-millionaire Stewart Donald is lining-up to invest in Sunderland?

Donald is keen to speak to individuals that would be keen on taking a minority shareholding in the Black Cats, and reports suggest that Sartori is one individual that he would be keen to speak to.

The new Sunderland owner confirmed he is set to jet off to Monaco to meet a potential investor over the weekend.

And he has previous history with Sartori after the 37-year-old tried to take over Oxford United - but just who is the multi-millionaire that Donald is targeting?

Who is Juan Sartori?

Sartori was born in Montevideo, Uruguay in 1981 and went on to live in France and Switzerland during his younger years.

He attended HEC - a world-renowned business school - and graduated with a degree in Business and Economics in 2002.

What are his business interests?

Sartori is the founder, and current president, of Union Group in Uruguay - the largest business of its kind in the country.

He started the business in 2006 as a blueberry farming business and then branched out into several different forms of agriculture.

The business has continued to expand and now deals with energy, forestry and real estate as well as holding interest in oil and gas.

He formed Union Agriculture Group in 2008 and then sold his existing business to that new company. By that point, he had already built up $1billion worth of assets.

Who are his connections?

While Sartori naturally has links with Donald, perhaps the most intriguing connection of his is with a Russian billionaire.

In 2015, Sartori married Ekaterina Rybolovleva, the daughter of Dmitry Rybolovlev.

Rybolovlev is the owner of AS Monaco and is currently placed 242nd on the Forbes Rich List with an estimated wealth of $6.8billion.

What is his previous history in football?

Sartori has previously tried to take over Oxford United - where he will have dealt with Donald.

The Uruguayan believed he could take the U's to the Premier League but his takeover bid was rejected by chairman Darryl Eales.

Speaking to the Oxford Mail after Eales rejected his formal offer, Sartori said: “I am sad about it, but what can you do?

“We worked a lot over the last three months and did due diligence, but it was Darryl’s decision to carry on at the club.

"We put forward a very strong project, a very credible project.

“It was a very ambitious project but we needed to buy the club to put it into action.

“We wanted to go as high as possible – the Championship and Premier League.

“Could we have made it? Of course. I have no doubt about it. I really think it is a great club with a great platform.”
