Gordon, who was a huge fans' favourite during his time with the club between 1978 and 1985, has died at the age of 70, after being diagnosed with dementia.
He joined the Reds from Leeds United and was part of our 1983 FA Cup-winning team, when Brighton & Hove Albion were defeated in a replay at Wembley.
When leaving in 1985, the ex-Scotland international had amassed 229 appearances for the club, scoring 26 goals from centre-half.
His coaching spell took him to Middlesbrough, where he worked under close pal and former Old Trafford team-mate Bryan Robson.
