Manchester United are reportedly planning to trial a new initiative this week in a bid to boost the atmosphere at Old Trafford.
A 'singing section' has been installed in the away end of the ground for tomorrow night's Champions League encounter against Real Sociedad.
It is believed that organisers have called on the 1,500 fans taking part in the trial to get to the ground early, according to BBC Sport.
The 'singing section' has come into force following the push from a number of fan groups.
