Crystal Palace co-owner Josh Harris is involved in the US private equity firm seeking to buy into Manchester United.

The Daily Mail says Harris has an involvement in private equity firm Apollo, who are in exclusive talks to purchase a minority stake in United.

It's yet to be established if Harris would be breaching Premier League ownership laws.

Harris holds a minority stake in Crystal Palace, believed to be around 18 percent, and is a director at the south London club.

Likewise, Harris co-founded Apollo and is currently listed on the company's website as sitting on the board of directors and executive committee.

This revelation arrives after it was revealed Newcastle United owners PIF are involved in Chelsea co-owners ClearLake Capital.
