An outbreak of foot and mouth disease threw sporting fixtures into complete chaos towards the end of the 2000/01 season. As has been mentioned Avec had withdrawn from Northern Ireland and the manufacture of Glentoran's playing kit was taken over by a firm from the north of England called Rossco. Rossco had already produced Linfield's shirt for a couple of seasons but they were not a well known brand even on the mainland. It's fair to say though that the shirt which they produced for Glentoran's showdown with the Blues in the 2001 Irish Cup final (and for the season which followed) was superb. Sponsorship of the Irish Cup had been taken over by Nationwide and so Glentoran were at last permitted to promote their club sponsor on the new shirt. Worn with black shorts and white socks with matching trim the 2001 Rossco shirt had everything. The Glens were back to wearing a more familiar shade of green, whilst red mesh panels under the sleeve gave the shirt a modern look. Glentoran would again lift the Irish Cup in this shirt defeating Linfield 1-0 in extra time thanks to a Michael Halliday goal. The final whistle again sparked memorable scenes of euphoria in the north stand.
This was every bit as stylish as the home shirt. The black away version retained the same design styling as the green jersey. The kit was worn more regularly than any other away strip during a campaign which saw Glentoran lift the County Antrim Shield but let the league slip away to down the M1 (by helicopter in fact) on the last day of the season to Portadown. Former Linfield and Portadown striker Garry Haylock signed for a 22 game spell during the season, whilst free scoring centre-forward Andy Smith was beginning to catch the eye. Chris Walker was named Glentoran Player of the Year and in Europe the Glens again gave a superb account of themselves away from home drawing 1-1 in Silkeborg Denmark with FC Midtjylland in the UEFA Cup (in the home version of this kit). With Mark Glendinning scoring on his debut.
