David joins Newcastle United after serving as President and Chief Operating Officer at Madison Square Garden Sports in the United States, where he led the business operations of the New York Knicks and New York Rangers.
Both are among the most valuable franchises in the National Basketball Association and National Hockey League respectively, and compete at the world-renowned Madison Square Garden in New York City.
Previously, as Global Head of Partnerships at Real Madrid, David served on the executive team as they cemented their place as one of the world's most valuable football clubs.
Earlier, he spent over two decades at Maple Leaf Sports & Entertainment as Chief Commercial Officer, overseeing commercial activities for the NHL's Toronto Maple Leafs and the NBA's Toronto Raptors.

"This club represents something truly special. It has extraordinary history and heritage, incredibly passionate supporters, and ownership, players and staff who are committed to excellence.
"Having worked with iconic teams across different countries, I understand what it takes to build sustainable success at the highest levels of global sport.
"I greatly admire what has been achieved by the club so far, and I am excited and motivated by what is ahead as we strive to position Newcastle United among the world's elite clubs."

"His experience and strategic capabilities will be invaluable as we continue to build on the club's presence locally and grow it globally on and off the pitch.
"David's leadership will be critical as we build upon what we have already achieved since the acquisition towards an exciting future and sustainable success.
"I would like to personally thank Darren Eales for his exceptional work and leadership, as well as his friendship, over the last three years."
