I don't recall us playing Man United
I have seen Gills v forest Green but that was a friendly, so agree with FGR and Salford for sure.
Manu was a testimonial for buster collins (utd team brought down by brucie). Been discussed many times on here.
Not competitive though.
We have played Melchester Rovers, I believe.
This inspired me to read up on the match from the excellent Gillingham Scrapbook. I particularly enjoyed the preview from the Liverpool Echo here: http://gillinghamfcscrapbook.co.uk/...ol Echo Cup Preview Part 1.jpg&season=1913-14You played Liverpool in 1914 fa cup and sadly lost.
We have played Melchester Rovers, I believe.
