Potential new Charlton Athletic owner makes Sunderland takeover claim

The 62-year-old Danish businessman is the founder, chairman and CEO of Zynex Inc, which produces medical devices and is based in Colorado.

Sandgaard’s bid to takeover Charlton is progressing following positive talks with East Street Investments and he has revealed his previous interest in several other English clubs including Swansea, Queens Park Rangers, Sunderland and Wigan Athletic.

Stewart Donald is looking to sell Sunderland and has slapped a price tag of £37.6million on the Black Cats.

Born in Denmark, Sandgaard moved to the United States in 1996.

In an interview with Sky Sports, Sandgaard has claimed he looked at several clubs – including Sunderland – before deciding it was Charlton he would target for a takeover.

"I started using my network in England to look at what was available," he told Sky Sports.

"I looked at everything from the bottom of the Premier League to the top of League One and have had a number of good friends putting out feelers for me.

"Obviously I looked at Sunderland with an incredible history, you call a club like Queens Park Rangers and you hear that they don't really need money. People were very confused down at Swansea.

"I looked at many things. Of course I looked very closely at Wigan and all along Charlton kept looking the best opportunity.

"The entire foundation is literally perfect. You can take the club to anything you want to."
