Former Aberdeen star Theo ten Caat insists putting Scott Brown on his coaching staff was Stephen Glass' "biggest mistake".
The Dutchman claims other players "can't trust" the veteran midfielder in the dressing room - and cited his own experience at Pittodrie.
He spent three years with the Dons between 1991 and 1994 and worked under boss Willie Miller and assistant Roy Aitken, who acted as player-assistant.
