Arsenal's chief executive Ian Gazidis will replace Manchester United's David Gill as the European Club Association's representative on UEFA's professional football strategy council.
The ECA executive board decided at its meeting in Moscow on Tusday to appoint Gazidis, who has been actively involved within the organisation since 2008.
He is currently chairman of the ECA legal advisory panel and member of the ECA competitions working group.
"I am delighted to be joining these important groups which are hugely influential in the future direction of the game in Europe," Gazidis said. "I am looking forward to representing the top European clubs in many important debates as we move ahead."
Gazidis' appointment comes following the decision of Gill to step down from his position on the ECA executive board.
Gill recently announced his candidacy for election to the UEFA executive committee in the coming year. Commenting on the appointment of Gazidis, ECA chairman Karl-Heinz Rummenigge said: "I am pleased to welcome Ivan Gazidis on the ECA Executive Board. His experience and distinct football knowledge will add a lot of value to ECA and European club football as a whole.
"At the same time, I would like to thank David Gill for his invaluable contribution to ECA over the last three years. On behalf of the ECA Executive Board, I wish him all the best for his future professional and personal life."
