When he first joined he did not get on with the then manager Dean Wilkins. This was partly due to Murray being recruited behind Wilkins' back, and partly due to them both being fairly shy, quiet blokes, Wilkins then had a mystery illness/ nervous breakdown (no one knows for sure) towards the end of the season, and Glenn was having domestic problems as his partner did not settle down south.
He put in a transfer request within a couple of months of signing due to his poor relationship with Wilkins. When Wilkins was sacked Mickey Adams persuaded him to stay, but a misdiagnosed hernia meant that Murray only played half the following season, and was sent off for elbowing a player, as well as collecting a lot of unnecessary yellows.
Start of following season he started on bench against Brentford. He had put in another transfer request as his partner had left him and taken the kid with her. When he came off the bench our 'witty' fans sang songs about his ex. At the end of the match he didn't 'respect' said fans by clapping them as he came off the pitch and they went mental at him.
Two more red cards that season, plus his ongoing undiagnosed injury restricted appearances. His shy demeanour was interpreted as aloofness and moody. Because he didn't run about like a headless chicken it was interpreted as laziness.
His full fitness and finding a new partner coincided with Gus arriving. Certainly his disciplinary record has improved, but his goals:games record was fairly consistent under the four managers he played under during his time at the club. A practically full season in 2010/11, coupled with domestic harmony, coming into his playing prime, a better style of play and better players around him, meant that he scored 22 last year.
Excellent summary!
