Lynch took over alongside brother Seamus ahead of the 2017/18 season with the Inver Reds languishing in the Championship and seven years later departs on the back of consecutive Premiership titles and with the County Antrim outfit competing in the UEFA Conference League.
According to Marshall Gillespie, 48-year-old Lynch took charge of 348 games, winning 203 and drawing 66 during a memorable tenure at Inver Park.
From title celebrations to European victories, here are some of Lynch’s best moments from his time at Larne.
