The North Down club's manager made a record 794 appearances for the Glens
Glentoran legend Colin Nixon will attempt to sink his old club on Friday night.
Nixon is now Ards manager and they face the Glens in a Danske Bank Premiership match in Bangor.
Victory would see the north Down side leapfrog their rivals into eighth place.
Nixon - who made a record 794 appearances for Glentoran - says it will be a special night, but with no room for sentiment...
Gary Haveron, who pipped Nixon to the manager's job at the Oval last year, says he wishes him well - although not this week.
The big match on Saturday sees leaders Crusaders hosting north Belfast rivals Cliftonville, currently third in the standings.

Meanwhile, the Bannsiders will be without striker Eoin Bradley for some time after he sustained broken ribs and a punctured lung last Saturday against Portadown.
Bradley's former Glenavon teammate Jonny Tuffey says everyone in the league wishes him a speedy recovery.
Tuffey and the Lurgan Blues have a Mid-Ulster derby away to the Ports on Saturday and in the other fixture Carrick Rangers entertain Dungannon Swifts.
