Organisers of Manchester United's singing section, which is set to be trialled in the encounter with Real Socieded on Wednesday night, are urging supporters to arrive 25 minutes before kick-off in the hope of improving the pre-match atmosphere.
The club have organised an experiment of sorts for this week's Champions League match, whereby an area of Old Trafford has been specifically designated for 1500 supporters who provide the most vocal support.
Tickets for the section were hugely oversubscribed and, although the introduction of a permanent singing section has been met with some opposition, the trial has clearly captured the imagination of some.
Manchester United have employed acoustic experts in a bid to discover which areas of the ground are most effective at generating sound, and the corners of Old Trafford - opposite the Stretford End - have been deemed the most suitable.
Andrew Kilduff, co-founder of Stretford End Flags, has been involved in the organisation of the signing section trial, and hopes this experiment could lead to improved performance of the pitch from Manchester United players.
"We would encourage supporters to get to Old Trafford 25 minutes before kick-off so we can make some noise as the players are warming up,"Kilduff said, as reported by The Guardian.
"Hopefully that atmosphere will transmit back to the players and it will improve their performance as well. We are aiming to police the area ourselves and hopefully, if it goes well, the singing section is something we can try again later in the season.
"Having it on a permanent basis is not as easy as people think. Nevertheless, if it works, it is something the club may look at because it will have a positive benefit for everyone."
