Police said the incident - which left a man with a head injury - happened shortly after the Scottish Cup fixture at Pittodrie on Sunday 3 March.
Officers have issued images of a man they wish to speak to.
He is described as being aged in his 20s, wearing a Rangers scarf and a black and grey jacket.
He has short fair-coloured hair.
