Woolwich hosted Liverpool a few seasons back. Lost 4-3.
And as someone mentioned, we lost to United 1-0 away, a few year back.
Yeah, i'm not a hundred percent sure on how much truth is behind what I even said now, just heard it somewhere. However the season we played United we were coming off a pretty average 6th place and were not considered much of a threat at the time. Likewise I think Liverpool finished 8th the season before playing Woolwich.
