Manchester United will open a singing section at Old Trafford for the visit of Real Sociedad in the Champions League on October 23.
The area will be located in the south-east corner of the stadium with Sociedad's fans moving to the East Stand.
Writing on Twitter, United midfielder Michael Carrick said: "Great idea to have a singing section. If I was going as a fan that's where I'd be."
Season ticket holders will get priority, while any tickets that remain unsold will be available to club members.
