I found a You Tube video that has brief highlights of the Saints v Mechelen matches. First time I remember seeing the away game footage, although my dad took me to the 2nd leg at Love Street. I was only 8 years old though, so cant remember too much about it now!
The video is a documentary about them winning the CWC that seasons, and shows all their games spliced with interviews with players and fans. The Saints segment starts at 15mins in, and shows a few seconds of the Saints travelling support in Belgium!
On a similar note. Did any Saints fans make the long journey to the Arctic circle for the First Round match in Tromso?
