During the course of United's 2007/08 Double campaign, Reds supporters showed how valuable their contribution can be.
Having roared the team to Moscow in the nail-biting semi-final win over Barcelona, the travelling Reds provided a raucous backing all through the final against Chelsea.
Once again, they held aloft a mosaic reading 'Believe', as they had against Barca, and that level of support proved inspirational as Sir Alex Ferguson's side clinched a dream Double.
Supporters group Stretford End Flags, as ever, are keen to harness the fans' power - and are already asking for ideas for next season's new banners.
SEF joined forces with United to create the Believe mosaic ahead of Barca's visit, and have created a number of banners and flags on display at the Stretford End in recent seasons.
Ideas and designs are being welcomed for a new banner in preparation for the 2008/09 season - ideally saluting Sir Alex Ferguson or last season's Double.
If you have any ideas, please visit www.stretfordendflags.com and submit your designs.
