Known as ‘LB’ (for ‘Long Body), Glenn’s association with Watford began a few years earlier, in the summer of 1989, arriving to shore up the defence as a 34-year-old centre-half on a free transfer from Newcastle United.
The Essex-born defender made 86 appearances for the Golden Boys, scoring three goals, and he proved to be a true leader in the team, foreshadowing his later move into management by skippering the side for much of his playing days at Vicarage Road.
He treated the Vicarage Road faithful to just occasional glimpses of the famed ‘Roeder Shuffle’ – a move for which he’d become noted elsewhere – which was a true crowd-pleasing move, seeing him ease past a stranded opponent with an idiosyncratic sleight-of-foot manoeuvre.
Glenn came through into the professional ranks at Leyton Orient and later led Queens Park Rangers out at the old Wembley Stadium for the 1982 FA Cup final against Tottenham Hotspur. He became captain at Newcastle United in the mid-late 80s, mentoring the emerging talents of Paul Gascoigne and Peter Beardsley at St. James’ Park.
